      ocfs2: free path in ocfs2_remove_inode_range() · 7aebff18
      由 Younger Liu 提交于 
      In ocfs2_remove_inode_range(), there is a memory leak.  The variable path
has allocated memory with ocfs2_new_path_from_et(), but it is not free.

      ocfs2: lighten up allocate transaction · 2b1e55c3
      由 Younger Liu 提交于 
      The issue scenario is as following:

When fallocating a very large disk space for a small file,
__ocfs2_extend_allocation attempts to get a very large transaction.  For
some journal sizes, there may be not enough room for this transaction,
and the fallocate will fail.

The patch below extends & restarts the transaction as necessary while
allocating space, and should work with even the smallest journal.  This
patch refers ext4 resize.

Test:
# mkfs.ocfs2 -b 4K -C 32K -T datafiles /dev/sdc
...(jounral size is 32M)
# mount.ocfs2 /dev/sdc /mnt/ocfs2/
# touch /mnt/ocfs2/1.log
# fallocate -o 0 -l 400G /mnt/ocfs2/1.log
fallocate: /mnt/ocfs2/1.log: fallocate failed: Cannot allocate memory
# tail -f /var/log/messages
[ 7372.278591] JBD: fallocate wants too many credits (2051 > 2048)
[ 7372.278597] (fallocate,6438,0):__ocfs2_extend_allocation:709 ERROR: status = -12

[ 7372.278607] (fallocate,6438,0):__ocfs2_change_file_space:1955 ERROR: status = -12
^C
With this patch, the test works well.

      aio: Kill aio_rw_vect_retry() · 73a7075e
      由 Kent Overstreet 提交于 
      This code doesn't serve any purpose anymore, since the aio retry
infrastructure has been removed.

This change should be safe because aio_read/write are also used for
synchronous IO, and called from do_sync_read()/do_sync_write() - and
there's no looping done in the sync case (the read and write syscalls).

      vfs: export lseek_execute() to modules · 46a1c2c7
      由 Jie Liu 提交于 
      For those file systems(btrfs/ext4/ocfs2/tmpfs) that support
SEEK_DATA/SEEK_HOLE functions, we end up handling the similar
matter in lseek_execute() to update the current file offset
to the desired offset if it is valid, ceph also does the
simliar things at ceph_llseek().

To reduce the duplications, this patch make lseek_execute()
public accessible so that we can call it directly from the
underlying file systems.

Thanks Dave Chinner for this suggestion.

[AV: call it vfs_setpos(), don't bring the removed 'inode' argument back]

v2->v1:
- Add kernel-doc comments for lseek_execute()
- Call lseek_execute() in ceph->llseek()

      userns: Modify dqget to take struct kqid · aca645a6
      由 Eric W. Biederman 提交于 
      Modify dqget to take struct kqid instead of a type and an identifier
pair.

Modify the callers of dqget in ocfs2 and dquot to take generate
a struct kqid so they can continue to call dqget.  The conversion
to create struct kqid should all be the final conversions that
are needed in those code paths.
