2007-09-11quota: fix infinite loopJan Kara
If we fail to start a transaction when releasing dquot, we have to call dquot_release() anyway to mark dquot structure as inactive. Otherwise we end in an infinite loop inside dqput().

2007-07-26fix inode_table test in ext234_check_descriptorsEric Sandeen
ext[234]_check_descriptors sanity checks block group descriptor geometry at mount time, testing whether the block bitmap, inode bitmap, and inode table reside wholly within the blockgroup. However, the inode table test is off by one so that if the last block in the inode table resides on the last block of the block group, the test incorrectly fails. This is because it tests the last block as (start + length) rather than (start + length - 1). This can be seen by trying to mount a filesystem made such as: mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024 which yields: EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)! EXT2-fs: group descriptors corrupted! There is a similar bug in e2fsprogs, patch already sent for that. (I wonder if inside(), outside(), and/or in_range() should someday be used in this and other tests throughout the ext filesystems...)

2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt
Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

2007-07-18ext4: Add nanosecond timestampsKalpak Shah
This patch adds nanosecond timestamps for ext4. This involves adding *time_extra fields to the ext4_inode to extend the timestamps to 64-bits. Creation time is also added by this patch. These extended fields will fit into an inode if the filesystem was formatted with large inodes (-I 256 or larger) and there are currently no EAs consuming all of the available space. For new inodes we always reserve enough space for the kernel's known extended fields, but for inodes created with an old kernel this might not have been the case. So this patch also adds the EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature flag(ro-compat so that older kernels can't create inodes with a smaller extra_isize). which indicates if the fields fitting inside s_min_extra_isize are available or not. If the expansion of inodes if unsuccessful then this feature will be disabled. This feature is only enabled if requested by the sysadmin. None of the extended inode fields is critical for correct filesystem operation.

2007-07-16ext4: statfs speed upBadari Pulavarty
This is a patch that speeds up statfs. It is very simple - the "overhead" calculation, which takes a huge amount of time for large filesystems, never changes unless the size of the filesystem itself changes. That means we can store it in memory and only recalculate if the filesystem has been resized (almost never). It also fixes a minor problem that we never update the on-disk superblock free blocks/inodes counts until the filesystem is unmounted. While not fatal, we may as well update that on disk when we have the information, and it makes things like debugfs and dumpe2fs report a bit more accurate info.

2007-07-16ext4: fix deadlock in ext4_remount() and orphan list handlingJan Kara
ext4_orphan_add() and ext4_orphan_del() functions lock sb->s_lock with a transaction started with ext4_mark_recovery_complete() waits for a transaction holding sb->s_lock, thus leading to a possible deadlock. At the moment we call ext4_mark_recovery_complete() from ext4_remount() we have done all the work needed for remounting and thus we are safe to drop sb->s_lock before we wait for transactions to commit. Note that at this moment we are still guarded by s_umount lock against other remounts/umounts.

2007-05-07slab allocators: Remove SLAB_DEBUG_INITIAL flagChristoph Lameter
I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

2007-02-11[PATCH] fix umask when noACL kernel meets extN tuned for ACLsHugh Dickins
Fix insecure default behaviour reported by Tigran Aivazian: if an ext2 or ext3 or ext4 filesystem is tuned to mount with "acl", but mounted by a kernel built without ACL support, then umask was ignored when creating inodes - though root or user has umask 022, touch creates files as 0666, and mkdir creates directories as 0777. This appears to have worked right until 2.6.11, when a fix to the default mode on symlinks (always 0777) assumed VFS applies umask: which it does, unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in s_flags according to s_mount_opt set according to def_mount_opts. We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test); but other filesystems only set MS_POSIXACL when ACLs are configured. We could fix this at another level; but it seems most robust to avoid setting the s_mount_opt flag in the first place (at the expense of more ifdefs). Likewise don't set the XATTR_USER flag when built without XATTR support.

2007-02-11[PATCH] ext4: refuse ro to rw remount of fs with orphan inodesEric Sandeen
In the rare case where we have skipped orphan inode processing due to a readonly block device, and the block device subsequently changes back to read-write, disallow a remount,rw transition of the filesystem when we have an unprocessed orphan inodes as this would corrupt the list. Ideally we should process the orphan inode list during the remount, but that's trickier, and this plugs the hole for now. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Cc: "Stephen C.

2006-10-11[PATCH] ext4: errors behaviour fixDmitry Mishin
Current error behaviour for ext2 and ext3 filesystems does not fully correspond to the documentation and should be fixed. According to man 8 mount, ext2 and ext3 file systems allow to set one of 3 different on-errors behaviours: ---- start of quote man 8 mount ---- errors=continue / errors=remount-ro / errors=panic Define the behaviour when an error is encountered. (Either ignore errors and just mark the file system erroneous and continue, or remount the file system read-only, or panic and halt the system.) The default is set in the filesystem superblock, and can be changed using tune2fs(8). ---- end of quote ---- However EXT3_ERRORS_CONTINUE is not read from the superblock, and thus ERRORS_CONT is not saved on the sbi->s_mount_opt. It leads to the incorrect handle of errors on ext3. Then we've checked corresponding code in ext2 and discovered that it is buggy as well: - EXT2_ERRORS_CONTINUE is not read from the superblock (the same); - parse_option() does not clean the alternative values and thus something like (ERRORS_CONT|ERRORS_RO) can be set; - if options are omitted, parse_option() does not set any of these options. Therefore it is possible to set any combination of these options on the ext2: - none of them may be set: EXT2_ERRORS_CONTINUE on superblock / empty mount options; - any of them may be set using mount options; - 2 any options may be set: by using EXT2_ERRORS_RO/EXT2_ERRORS_PANIC on the superblock and other value in mount options; - and finally all three options may be set by adding third option in remount. Currently ext2 uses these values only in ext2_error() and it is not leading to any noticeable troubles. However somebody may be discouraged when he will try to workaround EXT2_ERRORS_PANIC on the superblock by using errors=continue in mount options. This patch: EXT4_ERRORS_CONTINUE should be taken from the superblock as default value for error behaviour.

Also cast the arg to u64. do_div() is only defined on u64, and ext4_fsblk_t is supposed to be opaque. Note especially the changes to find_group_orlov().
