* xfs: fix indentation and other whitespace problems in scrub/repairDarrick J. Wong2018-07-231-10/+10
| | | | | | | | Now that we've shortened everything, fix up all the indentation and whitespace problems. There are no functional changes. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
* xfs: shorten struct xfs_scrub_context to struct xfs_scrubDarrick J. Wong2018-07-231-5/+5
| | | | | | | | | Shorten the name of the online fsck context structure. Whitespace damage will be fixed by a subsequent patch. There are no functional changes. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
* xfs: shorten xfs_scrub_ prefixDarrick J. Wong2018-07-231-53/+53
| | | | | | | | | | Shorten all the metadata checking xfs_scrub_ prefixes to xchk_. After this, the only xfs_scrub* symbols are the ones that pertain to both scrub and repair. Whitespace damage will be fixed in a subsequent patch. There are no functional changes. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
* xfs: convert to SPDX license tagsDave Chinner2018-06-061-15/+1

This does not change the license of any of the code, merely refers to the common, up-to-date license files in LICENSES/ This change was mostly scripted. fs/xfs/Makefile and fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected and modified by the following command: for f in `git grep -l "GNU General" fs/xfs/` ; do echo $f cat $f | awk -f hdr.awk > $f.new mv -f $f.new $f done And the hdr.awk script that did the modification (including detecting the difference between GPL-2.0 and GPL-2.0+ licenses) is as follows: $ cat hdr.awk BEGIN { hdr = 1.0 tag = "GPL-2.0" str = "" } /^ \* This program is free software/ { hdr = 2.0; next } /any later version./ { tag = "GPL-2.0+" next } /^ \*\// { if (hdr > 0.0) { print "// SPDX-License-Identifier: " tag print str print $0 str="" hdr = 0.0 next } print $0 next } /^ \* / { if (hdr > 1.0) next if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 next } /^ \*/ { if (hdr > 0.0) next print $0 next } // { if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 } END { } $ Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

* xfs: don't continue scrub if already corruptDarrick J. Wong2018-05-151-1/+2
| | | | | | | | If we've already decided that something is corrupt, we might as well abort all the loops and exit as quickly as possible. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
* xfs: remove xfs_buf parameter from inode scrub methodsDarrick J. Wong2018-03-231-1/+1
| | | | | | | | | Now that we no longer do raw inode buffer scrubbing, the bp parameter is no longer used anywhere we're dealing with an inode, so remove it and all the useless NULL parameters that go with it.

* xfs: pass inode number to xfs_scrub_ino_set_{preen,warning}Darrick J. Wong2017-11-091-1/+1
| | | | | | | | | | | | | | | There are two ways to scrub an inode -- calling xfs_iget and checking the raw inode core, or by loading the inode cluster buffer and checking the on-disk contents directly. The second method is only useful if _iget fails the verifiers; when this is the case, sc->ip is NULL and calling the tracepoint will cause a system crash. Therefore, pass the raw inode number directly into the _preen and _warning functions. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Darrick J.
