From e6075e984d100c12bb79267639c3f661d9788a67 Mon Sep 17 00:00:00 2001 From: Yongqiang Yang Date: Wed, 27 Jul 2011 20:40:18 -0400 Subject: [PATCH] ext4: remove lock_buffer in bclean() and setup_new_group_blocks() There is no need to lock the buffers since no one else should be touching these buffers besides the file system.
