[PATCH 43/56] ocfs2: Narrow the transaction for deleting xattrs from a bucket.

From: Mark Fasheh
Date: Mon Dec 22 2008 - 17:04:44 EST


From: Tao Ma <tao.ma@xxxxxxxxxx>

We move the transaction into the loop because in
ocfs2_remove_extent, we will double the credits in function
ocfs2_extend_rotate_transaction. So if we have a large loop
number, we will soon waste much the journal space.
