[Ocfs2-devel] [PATCH 1/1] Ocfs2-1.4: Backport mainline commit 'Journaling i_flags and i_orphaned_slot when adding inode to orphan dir' to ocfs2-1.4

[Tristan Ye]

Mainline commit 3939fda4b389993caf8741df5739b3e49f33a263

Currently, some callers were missing to journal the dirty inode after
adding it to orphan dir.

Now we're going to journal such modifications within the ocfs2_orphan_add()
itself, It's safe to do so, though some existing caller may duplicate this,
and it makes the logic look more straightforward anyway.
