CONFIG_FILE_LOCKING should not depend on CONFIG_BLOCK. This makes it possible to run complete systems out of a CONFIG_BLOCK=n initramfs on current kernels again (this last worked on 2.6.27.*).

2009-06-16remove put_cpu_no_resched()Thomas Gleixner
put_cpu_no_resched() is an optimization of put_cpu() which unfortunately can cause high latencies. The nfs iostats code uses put_cpu_no_resched() in a code sequence where a reschedule request caused by an interrupt between the get_cpu() and the put_cpu_no_resched() can delay the reschedule for at least HZ. The other users of put_cpu_no_resched() optimize correctly in interrupt code, but there is no real harm in using the put_cpu() function which is an alias for preempt_enable(). The extra check of the preemmpt count is not as critical as the potential source of missing a reschedule. Debugged in the preempt-rt tree and verified in mainline.

2009-06-16poll: avoid extra wakeups in select/pollEric Dumazet
After introduction of keyed wakeups Davide Libenzi did on epoll, we are able to avoid spurious wakeups in poll()/select() code too. For example, typical use of poll()/select() is to wait for incoming network frames on many sockets. But TX completion for UDP/TCP frames call sock_wfree() which in turn schedules thread. When scheduled, thread does a full scan of all polled fds and can sleep again, because nothing is really available. If number of fds is large, this cause significant load. This patch makes select()/poll() aware of keyed wakeups and useless wakeups are avoided. This reduces number of context switches by about 50% on some setups, and work performed by sofirq handlers.

2009-06-16writeback: skip new or to-be-freed inodesWu Fengguang
1) I_FREEING tests should be coupled with I_CLEAR The two I_FREEING tests are racy because clear_inode() can set i_state to I_CLEAR between the clear of I_SYNC and the test of I_FREEING. 2) skip I_WILL_FREE inodes in generic_sync_sb_inodes() to avoid possible races with generic_forget_inode() generic_forget_inode() sets I_WILL_FREE call writeback on its own, so generic_sync_sb_inodes() shall not try to step in and create possible races: generic_forget_inode inode->i_state |= I_WILL_FREE; spin_unlock(&inode_lock); generic_sync_sb_inodes() spin_lock(&inode_lock); __iget(inode); __writeback_single_inode // see non zero i_count may WARN here ==> WARN_ON(inode->i_state & I_WILL_FREE); spin_unlock(&inode_lock); may call generic_forget_inode again ==> iput(inode); The above race and warning didn't turn up because writeback_inodes() holds the s_umount lock, so generic_forget_inode() finds MS_ACTIVE and returns early. But we are not sure the UBIFS calls and future callers will guarantee that. So skip I_WILL_FREE inodes for the sake of safety.

2009-06-16oom: move oom_adj value from task_struct to mm_structDavid Rientjes
The per-task oom_adj value is a characteristic of its mm more than the task itself since it's not possible to oom kill any thread that shares the mm. If a task were to be killed while attached to an mm that could not be freed because another thread were set to OOM_DISABLE, it would have needlessly been terminated since there is no potential for future memory freeing. This patch moves oomkilladj (now more appropriately named oom_adj) from struct task_struct to struct mm_struct. This requires task_lock() on a task to check its oom_adj value to protect against exec, but it's already necessary to take the lock when dereferencing the mm to find the total VM size for the badness heuristic. This fixes a livelock if the oom killer chooses a task and another thread sharing the same memory has an oom_adj value of OOM_DISABLE. This occurs because oom_kill_task() repeatedly returns 1 and refuses to kill the chosen task while select_bad_process() will repeatedly choose the same task during the next retry. Taking task_lock() in select_bad_process() to check for OOM_DISABLE and in oom_kill_task() to check for threads sharing the same memory will be removed in the next patch in this series where it will no longer be necessary. Writing to /proc/pid/oom_adj for a kthread will now return -EINVAL since these threads are immune from oom killing already. They simply report an oom_adj value of OOM_DISABLE.

send_sigio_to_task() reads fown->signum several times, we can race with F_SETSIG which changes ->signum lockless.

2009-06-16jfs: fix regression preventing coalescing of extentsDave Kleikamp
Commit fec1878fe952b994125a3be7c94b1322db586f3b caused a regression in which contiguous blocks being allocated to the end of an extent were getting a new extent created. This typically results in files entirely made up of 1-block extents even though the blocks are contiguous on disk. Apparently grub doesn't handle a jfs file being fragmented into too many extents, since it refuses to boot a kernel from jfs that was created by the 2.6.30 kernel.

2009-06-15NLS: update handling of UnicodeAlan Stern
This patch (as1239) updates the kernel's treatment of Unicode. The character-set conversion routines are well behind the current state of the Unicode specification: They don't recognize the existence of code points beyond plane 0 or of surrogate pairs in the UTF-16 encoding. The old wchar_t 16-bit type is retained because it's still used in lots of places. This shouldn't cause any new problems; if a conversion now results in an invalid 16-bit code then before it must have yielded an undefined code. Difficult-to-read names like "utf_mbstowcs" are replaced with more transparent names like "utf8s_to_utf16s" and the ordering of the parameters is rationalized (buffer lengths come immediate after the pointers they refer to, and the inputs precede the outputs). Fortunately the low-level conversion routines are used in only a few places; the interfaces to the higher-level uni2char and char2uni methods have been left unchanged.

In many SoC implementations there are hardware registers can be read or write only. This extends the debugfs to enforce the file permissions for these types of registers by providing a set of fops which are read or write only. This assumes that the kernel developer knows more about the hardware than the user (even root users) -- which is normally true.

2009-06-15debugfs: dont stop on first failed recursive deleteSteven Rostedt
debugfs: dont stop on first failed recursive delete While running a while loop of removing a module that removes a debugfs directory with debugfs_remove_recursive, and at the same time doing a while loop of cat of a file in that directory, I would hit a point where somehow the cat of the file caused the remove to fail. The result is that other files did not get removed when the module was removed. I simple read of one of those file can oops the kernel because the operations to the file no longer exist (removed by module). The funny thing is that the file being cat'ed was removed. It was the siblings that were not. I see in the code to debugfs_remove_recursive there's a test that checks if the child fails to bail out of the loop to prevent an infinite loop. What this patch does is to still try any siblings in that directory. If all the siblings fail, or there are no more siblings, then we exit the loop. This fixes the above symptom, but... This is no full proof. It makes the debugfs_remove_recursive a bit more robust, but it does not explain why the one file failed. There may be some kind of delay deletion that makes the debugfs think it did not succeed. So this patch is more of a fix for the symptom but not the disease. This patch still makes the debugfs_remove_recursive more robust and until I can find out why the bug exists, this patch will keep the kernel from oopsing in most cases. Even after the cause is found I think this change can stand on its own and should be kept.

2009-06-15ocfs2: Adjust rightmost path in ocfs2_add_branch.Tao Ma
In ocfs2_add_branch, we use the rightmost rec of the leaf extent block to generate the e_cpos for the newly added branch. In the most case, it is OK but if the parent extent block's rightmost rec covers more clusters than the leaf does, it will cause kernel panic if we insert some clusters in it. The message is something like: (7445,1):ocfs2_insert_at_leaf:3775 ERROR: bug expression: le16_to_cpu(el->l_next_free_rec) >= le16_to_cpu(el->l_count) (7445,1):ocfs2_insert_at_leaf:3775 ERROR: inode 66053, depth 0, count 28, next free 28, rec.cpos 270, rec.clusters 1, insert.cpos 275, insert.clusters 1 [<fa7ad565>] ? ocfs2_do_insert_extent+0xb58/0xda0 [ocfs2] [<fa7b08f2>] ? ocfs2_insert_extent+0x5bd/0x6ba [ocfs2] [<fa7b1b8b>] ? ocfs2_add_clusters_in_btree+0x37f/0x564 [ocfs2] ... The panic can be easily reproduced by the following small test case (with bs=512, cs=4K, and I remove all the error handling so that it looks clear enough for reading). int main(int argc, char **argv) { int fd, i; char buf[5] = "test"; fd = open(argv[1], O_RDWR|O_CREAT); for (i = 0; i < 30; i++) { lseek(fd, 40960 * i, SEEK_SET); write(fd, buf, 5); } ftruncate(fd, 1146880); lseek(fd, 1126400, SEEK_SET); write(fd, buf, 5); close(fd); return 0; } The reason of the panic is that: the 30 writes and the ftruncate makes the file's extent list looks like: Tree Depth: 1 Count: 19 Next Free Rec: 1 ## Offset Clusters Block# 0 0 280 86183 SubAlloc Bit: 7 SubAlloc Slot: 0 Blknum: 86183 Next Leaf: 0 CRC32: 00000000 ECC: 0000 Tree Depth: 0 Count: 28 Next Free Rec: 28 ## Offset Clusters Block# Flags 0 0 1 143368 0x0 1 10 1 143376 0x0 ... 26 260 1 143576 0x0 27 270 1 143584 0x0 Now another write at 1126400(275 cluster) whiich will write at the gap between 271 and 280 will trigger ocfs2_add_branch, but the result after the function looks like: Tree Depth: 1 Count: 19 Next Free Rec: 2 ## Offset Clusters Block# 0 0 280 86183 1 271 0 143592 So the extent record is intersected and make the following operation bug out. This patch just try to remove the gap before we add the new branch, so that the root(branch) rightmost rec will cover the same right position. So in the above case, before adding branch the tree will be changed to Tree Depth: 1 Count: 19 Next Free Rec: 1 ## Offset Clusters Block# 0 0 271 86183 SubAlloc Bit: 7 SubAlloc Slot: 0 Blknum: 86183 Next Leaf: 0 CRC32: 00000000 ECC: 0000 Tree Depth: 0 Count: 28 Next Free Rec: 28 ## Offset Clusters Block# Flags 0 0 1 143368 0x0 1 10 1 143376 0x0 ... 26 260 1 143576 0x0 27 270 1 143584 0x0 And after branch add, the tree looks like Tree Depth: 1 Count: 19 Next Free Rec: 2 ## Offset Clusters Block# 0 0 271 86183 1 271 0 143592 Signed-off-by: Tao Ma <tao.ma@oracle.com> Acked-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

2009-06-14ramfs: ignore unknown mount optionsMike Frysinger
On systems where CONFIG_SHMEM is disabled, mounting tmpfs filesystems can fail when tmpfs options are used. This is because tmpfs creates a small wrapper around ramfs which rejects unknown options, and ramfs itself only supports a tiny subset of what tmpfs supports. This makes it pretty hard to use the same userspace systems across different configuration systems. As such, ramfs should ignore the tmpfs options when tmpfs is merely a wrapper around ramfs. This used to work before commit c3b1b1cbf0 as previously, ramfs would ignore all options. But now, we get: ramfs: bad mount option: size=10M mount: mounting mdev on /dev failed: Invalid argument Another option might be to restore the previous behavior, where ramfs simply ignored all unknown mount options ... which is what Hugh prefers.
