* xfs: remove unused header filesEric Sandeen2019-06-281-5/+0
| | | | | | | | | | | | | | | | There are many, many xfs header files which are included but unneeded (or included twice) in the xfs code, so remove them. nb: xfs_linux.h includes about 9 headers for everyone, so those explicit includes get removed by this. I'm not sure what the preference is, but if we wanted explicit includes everywhere, a followup patch could remove those xfs_*.h includes from xfs_linux.h and move them into the files that need them. Or it could be left as-is. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>
* xfs: use buf ops magic to detect btree block typeDarrick J. Wong2019-02-111-6/+0
| | | | | | | | | Now that we encode block magic numbers in all the buffer ops, use that for block type detection in the ag header repair code instead of encoding magics directly in the repair code.

* xfs: split up allocation btree verifierBrian Foster2019-02-111-2/+2
| | | | | | | | | | | | Similar to the inode btree verifier, the same allocation btree verifier structure is shared between the by-bno (bnobt) and by-size (cntbt) btrees. This prevents the ability to distinguish magic values between them. Separate the verifier into two, one for each tree, and assign them appropriately. No functional changes.

* xfs: create a separate finobt verifierBrian Foster2019-02-111-1/+1
| | | | | | | | | | | | The inobt verifier is reused for the inobt and finobt, which prevents the ability to distinguish between magic values on a per-tree basis. Create a separate finobt structure in preparation for changes to enforce the appropriate magic value for the associated tree. This patch has no functional change.

* xfs: remove xfs_rmap_ag_owner and friendsDarrick J. Wong2018-12-121-3/+2
| | | | | | | | | | Owner information for static fs metadata can be defined readonly at build time because it never changes across filesystems. This enables us to reduce stack usage (particularly in scrub) because we can use the statically defined oinfo structures. Signed-off-by: Darrick J.

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.
