From b10370585349d364ff3c550afa7922e6e21f029d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 19 Sep 2011 14:55:51 +0000 Subject: xfs: unlock the inode before log force in xfs_fsync Only read the LSN we need to push to with the ilock held, and then release it before we do the log force to improve concurrency. This also removes the only direct caller of _xfs_trans_commit, thus allowing it to be merged into the plain xfs_trans_commit again.
