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_symlink.c | 30 +++++++++++++++--------------- 1 file changed, 15 insertions(+), 15 deletions(-) (limited to 'fs/xfs/xfs_symlink.c') diff --git a/fs/xfs/xfs_symlink.c b/fs/xfs/xfs_symlink.c index c2c8173d1634..6a944a2cd36f 100644 --- a/fs/xfs/xfs_symlink.c +++ b/fs/xfs/xfs_symlink.c @@ -76,15 +76,15 @@ xfs_readlink_bmap( bp = xfs_buf_read(mp->m_ddev_targp, d, BTOBB(byte_cnt), 0, &xfs_symlink_buf_ops); if (!bp) - return ENOMEM; + return -ENOMEM; error = bp->b_error; if (error) { xfs_buf_ioerror_alert(bp, __func__); xfs_buf_relse(bp); /* bad CRC means corrupted metadata */ - if (error == EFSBADCRC) - error = EFSCORRUPTED; + if (error == -EFSBADCRC) + error = -EFSCORRUPTED; goto out; } byte_cnt = XFS_SYMLINK_BUF_SPACE(mp, byte_cnt); @@ -95,7 +95,7 @@ xfs_readlink_bmap( if (xfs_sb_version_hascrc(&mp->m_sb)) { if (!xfs_symlink_hdr_ok(ip->i_ino, offset, byte_cnt, bp)) { - error = EFSCORRUPTED; + error = -EFSCORRUPTED; xfs_alert(mp, "symlink header does not match required off/len/owner (0x%x/Ox%x,0x%llx)", offset, byte_cnt, ip->i_ino); @@ -135,7 +135,7 @@ xfs_readlink( trace_xfs_readlink(ip); if (XFS_FORCED_SHUTDOWN(mp)) - return EIO; + return -EIO; xfs_ilock(ip, XFS_ILOCK_SHARED); @@ -148,7 +148,7 @@ xfs_readlink( __func__, (unsigned long long) ip->i_ino, (long long) pathlen); ASSERT(0); - error = EFSCORRUPTED; + error = -EFSCORRUPTED; goto out; } @@ -203,14 +203,14 @@ xfs_symlink( trace_xfs_symlink(dp, link_name); if (XFS_FORCED_SHUTDOWN(mp)) - return EIO; + return -EIO; /* * Check component lengths of the target path name. */ pathlen = strlen(target_path); if (pathlen >= MAXPATHLEN) /* total string too long */ - return ENAMETOOLONG; + return -ENAMETOOLONG; udqp = gdqp = NULL; prid = xfs_get_initial_prid(dp); @@ -238,7 +238,7 @@ xfs_symlink( fs_blocks = xfs_symlink_blocks(mp, pathlen); resblks = XFS_SYMLINK_SPACE_RES(mp, link_name->len, fs_blocks); error = xfs_trans_reserve(tp, &M_RES(mp)->tr_symlink, resblks, 0); - if (error == ENOSPC && fs_blocks == 0) { + if (error == -ENOSPC && fs_blocks == 0) { resblks = 0; error = xfs_trans_reserve(tp, &M_RES(mp)->tr_symlink, 0, 0); } @@ -254,7 +254,7 @@ xfs_symlink( * Check whether the directory allows new symlinks or not. */ if (dp->i_d.di_flags & XFS_DIFLAG_NOSYMLINKS) { - error = EPERM; + error = -EPERM; goto error_return; } @@ -284,7 +284,7 @@ xfs_symlink( error = xfs_dir_ialloc(&tp, dp, S_IFLNK | (mode & ~S_IFMT), 1, 0, prid, resblks > 0, &ip, NULL); if (error) { - if (error == ENOSPC) + if (error == -ENOSPC) goto error_return; goto error1; } @@ -348,7 +348,7 @@ xfs_symlink( bp = xfs_trans_get_buf(tp, mp->m_ddev_targp, d, BTOBB(byte_cnt), 0); if (!bp) { - error = ENOMEM; + error = -ENOMEM; goto error2; } bp->b_ops = &xfs_symlink_buf_ops; @@ -489,7 +489,7 @@ xfs_inactive_symlink_rmt( XFS_FSB_TO_DADDR(mp, mval[i].br_startblock), XFS_FSB_TO_BB(mp, mval[i].br_blockcount), 0); if (!bp) { - error = ENOMEM; + error = -ENOMEM; goto error_bmap_cancel; } xfs_trans_binval(tp, bp); @@ -562,7 +562,7 @@ xfs_inactive_symlink( trace_xfs_inactive_symlink(ip); if (XFS_FORCED_SHUTDOWN(mp)) - return EIO; + return -EIO; xfs_ilock(ip, XFS_ILOCK_EXCL); @@ -580,7 +580,7 @@ xfs_inactive_symlink( __func__, (unsigned long long)ip->i_ino, pathlen); xfs_iunlock(ip, XFS_ILOCK_EXCL); ASSERT(0); - return EFSCORRUPTED; + return -EFSCORRUPTED; } if (ip->i_df.if_flags & XFS_IFINLINE) { -- cgit v1.2.3
