2008-10-23[SCSI] sd: fix computation of the full size of the deviceH. Peter Anvin
When computing the full size of the device, we need to cast sdkp->capacity before shifting, since in some configurations sector_t can be a 32-bit number. Also, change ffz(~x) to the more idiomatic ilog2(x). Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-10-23[SCSI] lib: string_get_size(): don't hang on zero; no decimals on exactH. Peter Anvin
We would hang forever when passing a zero to string_get_size(). Furthermore, string_get_size() would produce decimals on a value small enough to be exact. Finally, a few formatting issues are inconsistent with standard SI style guidelines. - If the value is less than the divisor, skip the entire rounding step. This prints out all small values including zero as integers, without decimals. - Add a space between the value and the symbol for the unit, consistent with standard SI practice. - Lower case k in kB since we are talking about powers of 10. - Finally, change "int" to "unsigned int" in one place to shut up a gcc warning when compiling the code out-of-kernel for testing.

2008-10-23[SCSI] sd: remove command-size switching codeAlan Stern
This patch (as1138) removes from sd.c some old code for switching from 10-byte commands to 6-byte commands. This code is redundant -- the switching for READ and WRITE is already handled in scsi_io_completion() and the switching for MODE SENSE is already handled in scsi_mode_sense(). (There is no comparable switch for MODE SELECT, but I doubt one is needed.) Furthermore the other handlers do a better job; they check for appropriate ASC and ASCQ values before blindly switching the size. The code in sd.c is known to cause problems with some devices by switching when it shouldn't.

2008-10-23[SCSI] sd: Fix handling of NO_SENSE check conditionJamie Wellnitz
The current handling of NO_SENSE check condition is the same as RECOVERED_ERROR, and assumes that in both cases, the I/O was fully transferred. We have seen cases of arrays returning with NO_SENSE (no error), but the I/O was not completely transferred, thus residual set. Thus, rather than return good_bytes as the entire transfer, set good_bytes to 0, so that the midlayer then applies the residual in calculating the transfer, and for sd, will fail the I/O and fall into a retry path.

2008-10-23[SCSI] export busy state via q->lld_busy_fn()Kiyoshi Ueda
This patch implements q->lld_busy_fn() for scsi mid layer to export its busy state for request stacking drivers. For efficiency, no lock is taken to check the busy state of shost/starget/sdev, since the returned value is not guaranteed and may be changed after request stacking drivers call the function, regardless of taking lock or not. When scsi can't dispatch I/Os anymore and needs to kill I/Os (e.g. !sdev), scsi needs to return 'not busy'. Otherwise, request stacking drivers may hold requests forever.

2008-10-23memcg: fix page_cgroup allocationKAMEZAWA Hiroyuki
page_cgroup_init() is called from mem_cgroup_init(). But at this point, we cannot call alloc_bootmem(). (and this caused panic at boot.) This patch moves page_cgroup_init() to init/main.c. Time table is following: == parse_args(). # we can trust mem_cgroup_subsys.disabled bit after this. .... cgroup_init_early() # "early" init of cgroup. .... setup_arch() # memmap is allocated. ... page_cgroup_init(); mem_init(); # we cannot call alloc_bootmem after this. .... cgroup_init() # mem_cgroup is initialized. == Before page_cgroup_init(), mem_map must be initialized. So, I added page_cgroup_init() to init/main.c directly. (*) maybe this is not very clean but - cgroup_init_early() is too early - in cgroup_init(), we have to use vmalloc instead of alloc_bootmem(). use of vmalloc area in x86-32 is important and we should avoid very large vmalloc() in x86-32. So, we want to use alloc_bootmem() and added page_cgroup_init() directly to init/main.c [akpm@linux-foundation.org: remove unneeded/bad mem_cgroup_subsys declaration] [akpm@linux-foundation.org: fix build] Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com> Tested-by: Balbir Singh <balbir@linux.vnet.ibm.com> Signed-off-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-10-23jbd: abort instead of waiting for nonexistent transactionsDuane Griffin
The __log_wait_for_space function sits in a loop checkpointing transactions until there is sufficient space free in the journal. However, if there are no transactions to be processed (e.g. because the free space calculation is wrong due to a corrupted filesystem) it will never progress. Check for space being required when no transactions are outstanding and abort the journal instead of endlessly looping.

2008-10-23ext3: add checks for errors from jbdHidehiro Kawai
If the journal has aborted due to a checkpointing failure, we have to keep the contents of the journal space. Otherwise, the filesystem will lose uncheckpointed metadata completely and become inconsistent. To avoid this, we need to keep needs_recovery flag if checkpoint has failed. With this patch, ext3_put_super() detects a checkpointing failure from the return value of journal_destroy(), then it invokes ext3_abort() to make the filesystem read only and keep needs_recovery flag. Errors from journal_flush() are also handled by this patch in some places.

2008-10-23jbd: fix error handling for checkpoint ioHidehiro Kawai
When a checkpointing IO fails, current JBD code doesn't check the error and continue journaling. This means latest metadata can be lost from both the journal and filesystem. This patch leaves the failed metadata blocks in the journal space and aborts journaling in the case of log_do_checkpoint(). To achieve this, we need to do: 1. don't remove the failed buffer from the checkpoint list where in the case of __try_to_free_cp_buf() because it may be released or overwritten by a later transaction 2. log_do_checkpoint() is the last chance, remove the failed buffer from the checkpoint list and abort the journal 3. when checkpointing fails, don't update the journal super block to prevent the journaled contents from being cleaned. For safety, don't update j_tail and j_tail_sequence either 4. when checkpointing fails, notify this error to the ext3 layer so that ext3 don't clear the needs_recovery flag, otherwise the journaled contents are ignored and cleaned in the recovery phase 5. if the recovery fails, keep the needs_recovery flag 6. prevent cleanup_journal_tail() from being called between __journal_drop_transaction() and journal_abort() (a race issue between journal_flush() and __log_wait_for_space() Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Acked-by: Jan Kara <jack@suse.cz> Cc: <linux-ext4@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
