tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

ocfs2: simplify ocfs2_invalidatepage() and ocfs2_releasepage()

2013-11-13T03:09:02+00:00

Ocfs2 doesn't do data journalling.  Thus its ->invalidatepage and
->releasepage functions never get called on buffers that have journal
heads attached.  So just use standard variants of functions from
buffer.c.

ocfs2: convert use of typedef ctl_table to struct ctl_table

2013-11-13T03:09:02+00:00

This typedef is unnecessary and should just be removed.

ocfs2: fix possible double free in ocfs2_write_begin_nolock

2013-11-13T03:09:02+00:00

When ocfs2_write_cluster_by_desc() failed in ocfs2_write_begin_nolock()
because of ENOSPC, it goes to out_quota, freeing data_ac(meta_ac).  Then
it calls ocfs2_try_to_free_truncate_log() to free space.  If enough
space freed, it will try to write again.  Unfortunately, some error
happenes before ocfs2_lock_allocators(), it goes to out and free
data_ac(meta_ac) again.

ocfs2: add missing errno in ocfs2_ioctl_move_extents()

2013-11-13T03:09:02+00:00

If the file is not regular or writeable, it should return errno(EPERM).

This patch is based on 85a258b70d ("ocfs2: fix error handling in
ocfs2_ioctl_move_extents()").

ocfs2: do not call brelse() if group_bh is not initialized in ocfs2_group_add()

2013-11-13T03:09:01+00:00

If group_bh is not initialized, there is no need to release.  This
problem does not cause anything wrong, but the patch would make the code
more logical.

ocfs2: rollback transaction in ocfs2_group_add()

2013-11-13T03:09:01+00:00

If ocfs2_journal_access_di() fails, group->bg_next_group should rollback.
Otherwise, there would be a inconsistency between group_bh and main_bm_bh.

We already have find_last_bit().  So just use it as described in the
comment.
