* vfs: Use const for kernel parser tableSteven Whitehouse2008-10-131-1/+1
| | | | | | | | | | | | | | This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.

* ocfs2: fiemap supportMark Fasheh2008-10-035-62/+306
| | | | | | | | | | | | | | Plug ocfs2 into ->fiemap. Some portions of ocfs2_get_clusters() had to be refactored so that the extent cache can be skipped in favor of going directly to the on-disk records. This makes it easier for us to determine which extent is the last one in the btree. Also, I'm not sure we want to be caching fiemap lookups anyway as they're not directly related to data read/write.

* ocfs2: Fix a bug in direct IO read.Tao Ma2008-09-101-1/+1
| | | | | | | | | | | | | | | | | | | ocfs2 will become read-only if we try to read the bytes which pass the end of i_size. This can be easily reproduced by following steps: 1. mkfs a ocfs2 volume with bs=4k cs=4k and nosparse. 2. create a small file(say less than 100 bytes) and we will create the file which is allocated 1 cluster. 3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit. 4. The ocfs2 volume becomes read-only and dmesg shows: OCFS2: ERROR (device sda13): ocfs2_direct_IO_get_blocks: Inode 66010 has a hole at block 1 File system is now read-only due to the potential of on-disk corruption. Please run fsck.ocfs2 once the file system is unmounted. So suppress the ERROR message. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>

* ocfs2: correctly set i_blocks after inline dir gets expandedMark Fasheh2008-08-221-1/+6
| | | | | | | | | | | | | We were setting i_blocks based on allocation before the extent insert, which is wrong as the value is a calculation based on ip_clusters which gets updated as a result of the insert. This patch moves the line in question to just after the call to ocfs2_insert_extent(). Without this fix, inline directories were temporarily having an i_blocks value of zero immediately after expansion to extents.

* [PATCH 2/2] ocfs2: Fix race between mount and recoverySunil Mushran2008-07-314-42/+148
| | | | | | | | | | | | | | | | | | | | | | | | As the fs recovery is asynchronous, there is a small chance that another node can mount (and thus recover) the slot before the recovery thread gets to it. If this happens, the recovery thread will block indefinitely on the journal/slot lock as that lock will be held for the duration of the mount (by design) by the node assigned to that slot. The solution implemented is to keep track of the journal replays using a recovery generation in the journal inode, which will be incremented by the thread replaying that journal. The recovery thread, before attempting the blocking lock on the journal/slot lock, will compare the generation on disk with what it has cached and skip recovery if it does not match. This bug appears to have been inadvertently introduced during the mount/umount vote removal by mainline commit 34d024f84345807bf44163fac84e921513dde323. In the mount voting scheme, the messaging would indirectly indicate that the slot was being recovered.

* configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker2008-07-172-19/+7
| | | | | | | | | | | | | | | | | | The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a mmap_truncate bug which was found by ocfs2 test suite. In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races mmap writes and truncates from multiple processes. While the test is running, a stat from another node forces writeout, causing an oops in ocfs2_get_block() because it sees a buffer to write which isn't allocated. This patch fixed the bug by clear dirty and uptodate bits in buffer, leave the buffer unmapped and return. Fix is suggested by Mark Fasheh, and I code up the patch.

* ocfs2: Correct merge of 52f7c21 (Move /sys/o2cb to /sys/fs/o2cb)Joel Becker2008-04-301-1/+1
| | | | | | | | | | | | Commit 52f7c21b613f80cb425d115c9e5b4ed958a133c0 was intended to move /sys/o2cb to /sys/fs/o2cb, providing /sys/o2cb as a symlink for backwards compatibility. However, the merge apparently added the symlink but failed to move the directory, resulting in a duplicate filename error. It's a one-line change that was missing.

* mm: bdi: add separate writeback accounting capabilityMiklos Szeredi2008-04-301-1/+1
| | | | | | | | | | | | | | | | | Add a new BDI capability flag: BDI_CAP_NO_ACCT_WB. If this flag is set, then don't update the per-bdi writeback stats from test_set_page_writeback() and test_clear_page_writeback(). Misc cleanups: - convert bdi_cap_writeback_dirty() and friends to static inline functions - create a flag that includes all three dirty/writeback related flags, since almst all users will want to have them toghether Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* [PATCH] r/o bind mounts: elevate write count for ioctls()Dave Hansen2008-04-191-5/+6
| | | | | | | | | | | | | Some ioctl()s can cause writes to the filesystem. Take these, and make them use mnt_want/drop_write() instead.

* ocfs2/net: Add debug interface to o2netSunil Mushran2008-04-186-3/+569
| | | | | | | | | | | | | | | This patch exposes o2net information via debugfs. The information includes the list of sockets (sock_containers) as well as the list of outstanding messages (send_tracking). Useful for o2dlm debugging. (This patch is derived from an earlier one written by Zach Brown that exposed the same information via /proc.)

* ocfs2: Only build ocfs2/dlm with the o2cb stack moduleMark Fasheh2008-04-181-1/+1
| | | | | | | | | | | fs/ocfs2/dlm/ocfs2_dlm.ko and fs/ocfs2/dlm/ocfs2_dlmfs.ko get built if CONFIG_FS_OCFS2 is specified. This isn't quite how it should happen any more - the "o2cb" dlm modules should only be built if CONFIG_FS_OCFS2_O2CB is set, so update the dlm Makefile accordingly.
