Subject: ocfs2: Narrow the transaction for deleting xattrs from a bucket.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=88c3b0622acf82c7c86fbc066e81e15edc7c1685;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ocfs2: Narrow the transaction for deleting xattrs from a bucket.

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.
