From 537a03103c67c4688b1e8e6671ad119aec5e2efb Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Sun, 20 Mar 2011 22:57:02 -0400 Subject: [PATCH] ext4: unify the ext4_handle_release_buffer() api There are two wrapper functions which do exactly the same thing: ext4_journal_release_buffer(), and ext4_handle_release_buffer(). In addition, ext4_xattr_block_set() calls jbd2_journal_release_buffer() directly. Unify all of the code to use ext4_handle_release_buffer(), and get rid of ext4_journal_release_buffer().
