From 340a0a01b9675a16201cc4fc4a210eb5b3bc11ce Mon Sep 17 00:00:00 2001 From: Markus Trippelsdorf Date: Sun, 24 Jul 2011 14:03:30 +0200 Subject: xfs: Fix wrong return value of xfs_file_aio_write The fsync prototype change commit 02c24a82187d accidentally overwrote the ssize_t return value of xfs_file_aio_write with 0 for SYNC type writes. Fix this by checking if an error occured when calling xfs_file_fsync and only change the return value in this case. In addition xfs_file_fsync actually returns a normal negative error, so fix this, too.
