From 2451337dd043901b5270b7586942abe564443e3d Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 25 Jun 2014 14:58:08 +1000 Subject: xfs: global error sign conversion Convert all the errors the core XFs code to negative error signs like the rest of the kernel and remove all the sign conversion we do in the interface layers. Errors for conversion (and comparison) found via searches like: $ git grep " E" fs/xfs $ git grep "return E" fs/xfs $ git grep " E[A-Z].*;$" fs/xfs Negation points found via searches like: $ git grep "= -[a-z,A-Z]" fs/xfs $ git grep "return -[a-z,A-D,F-Z]" fs/xfs $ git grep " -[a-z].*;" fs/xfs [ with some bits I missed from Brian Foster ] Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner --- fs/xfs/xfs_discard.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'fs/xfs/xfs_discard.c') diff --git a/fs/xfs/xfs_discard.c b/fs/xfs/xfs_discard.c index 3fee16e63f3a..13d08a1b390e 100644 --- a/fs/xfs/xfs_discard.c +++ b/fs/xfs/xfs_discard.c @@ -124,7 +124,7 @@ xfs_trim_extents( } trace_xfs_discard_extent(mp, agno, fbno, flen); - error = -blkdev_issue_discard(bdev, dbno, dlen, GFP_NOFS, 0); + error = blkdev_issue_discard(bdev, dbno, dlen, GFP_NOFS, 0); if (error) goto out_del_cursor; *blocks_trimmed += flen; @@ -195,7 +195,7 @@ xfs_ioc_trim( end_agno = xfs_daddr_to_agno(mp, end); for (agno = start_agno; agno <= end_agno; agno++) { - error = -xfs_trim_extents(mp, agno, start, end, minlen, + error = xfs_trim_extents(mp, agno, start, end, minlen, &blocks_trimmed); if (error) last_error = error; @@ -222,11 +222,11 @@ xfs_discard_extents( trace_xfs_discard_extent(mp, busyp->agno, busyp->bno, busyp->length); - error = -blkdev_issue_discard(mp->m_ddev_targp->bt_bdev, + error = blkdev_issue_discard(mp->m_ddev_targp->bt_bdev, XFS_AGB_TO_DADDR(mp, busyp->agno, busyp->bno), XFS_FSB_TO_BB(mp, busyp->length), GFP_NOFS, 0); - if (error && error != EOPNOTSUPP) { + if (error && error != -EOPNOTSUPP) { xfs_info(mp, "discard failed for extent [0x%llu,%u], error %d", (unsigned long long)busyp->bno, -- cgit v1.2.3
