Message-Id: <1229723644-13630-16-git-send-email-mfasheh@suse.com> Date: Fri, 19 Dec 2008 13:53:34 -0800 From: Mark Fasheh <mfasheh@...e.com> To: linux-kernel@...r.kernel.org Cc: ocfs2-devel@....oracle.com, Joel Becker <joel.becker@...cle.com>, Tao Ma <tao.ma@...cle.com>, Mark Fasheh <mfasheh@...e.com> Subject: [PATCH 15/45] ocfs2/xattr: Only set buffer update if it doesn't exist in cache. From: Tao Ma <tao.ma@...cle.com> When we call ocfs2_init_xattr_bucket, we deem that the new buffer head will be written to disk immediately, so we just use sb_getblk. But in some cases the buffer may have already been in ocfs2 uptodate cache, so we only call ocfs2_set_buffer_uptodate if the buffer head isn't in the cache.
