These new callbacks notify the dlm user about lock recovery. GFS2, and possibly others, need to be aware of when the dlm will be doing lock recovery for a failed lockspace member.

2011-12-02ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita2-5/+52
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

2011-11-17ocfs2: Add a missing journal credit in ocfs2_link_credits() -v2Xiaowei.Hu1-2/+3
With indexed_dir enabled, ocfs2 maintains a list of dirblocks having space. The credit calculation in ocfs2_link_credits() did not correctly account for adding an entry that exactly fills a dirblock that triggers removing that dirblock by changing the pointer in the previous block in the list. The credit calculation did not account for that previous block. To expose, do: mkfs.ocfs2 -b 512 -M local /dev/sdX mount /dev/sdX /ocfs2 mkdir /ocfs2/linkdir touch /ocfs2/linkdir/file1 for i in `seq 1 29` ; do link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklink$i; done rm -f /ocfs2/linkdir/linklinklinklinklinklink10 sleep 8 link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Note: The link names have been crafted for a 512 byte blocksize. Reproducing with a larger blocksize will require longer (or more) links. The sleep is important. We want jbd2 to commit the transaction so that the missing block does not piggy back on account of the previous transaction.

2011-11-17ocfs2: make direntry invalid when deleting itWengang Wang1-2/+1
When we deleting a direntry from a directory, if it's the first in a block we invalid it by setting inode to 0; otherwise, we merge the deleted one to the prior and contiguous direntry. And we don't truncate directories. There is a problem for the later case since inode is not set to 0. This problem happens when the caller passes a file position as parameter to ocfs2_dir_foreach_blk(). If the position happens to point to a stale(not the first, deleted in betweens of ocfs2_dir_foreach_blk()s) direntry, we are not able to recognize its staleness. So that we treat it as a live one wrongly. The fix is to set inode to 0 in both cases indicating the direntry is stale. This won't introduce additional IOs.

2011-07-28ocfs2: Avoid livelock in ocfs2_readpage()Jan Kara1-0/+8
When someone writes to an inode, readers accessing the same inode via ocfs2_readpage() just busyloop trying to get ip_alloc_sem because do_generic_file_read() looks up the page again and retries ->readpage() when previous attempt failed with AOP_TRUNCATED_PAGE. When there are enough readers, they can occupy all CPUs and in non-preempt kernel the system is deadlocked because writer holding ip_alloc_sem is never run to release the semaphore. Fix the problem by making reader block on ip_alloc_sem to break the busy loop. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Joel Becker <jlbec@evilplan.org>
2011-07-28ocfs2: serialize unaligned aioMark Fasheh5-2/+73
Fix a corruption that can happen when we have (two or more) outstanding aio's to an overlapping unaligned region. Ext4 (e9e3bcecf44c04b9e6b505fd8e2eb9cea58fb94d) and xfs recently had to fix similar issues. In our case what happens is that we can have an outstanding aio on a region and if a write comes in with some bytes overlapping the original aio we may decide to read that region into a page before continuing (typically because of buffered-io fallback). Since we have no ordering guarantees with the aio, we can read stale or bad data into the page and then write it back out. If the i/o is page and block aligned, then we avoid this issue as there won't be any need to read data from disk. I took the same approach as Eric in the ext4 patch and introduced some serialization of unaligned async direct i/o. I don't expect this to have an effect on the most common cases of AIO. Unaligned aio will be slower though, but that's far more acceptable than data corruption. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <jlbec@evilplan.org>
2011-07-26ocfs2: Implement llseek()Sunil Mushran3-2/+151
ocfs2 implements its own llseek() to provide the SEEK_HOLE/SEEK_DATA functionality. SEEK_HOLE sets the file pointer to the start of either a hole or an unwritten (preallocated) extent, that is greater than or equal to the supplied offset. SEEK_DATA sets the file pointer to the start of an allocated extent (not unwritten) that is greater than or equal to the supplied offset. If the supplied offset is on a desired region, then the file pointer is set to it. Offsets greater than or equal to the file size return -ENXIO. Unwritten (preallocated) extents are considered holes because the file system treats reads to such regions in the same way as it does to holes. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
