* xfs: refactor intent item RECOVERED flag into the log itemDarrick J. Wong2020-05-081-6/+0
| | | | | | | | | | Rename XFS_{EFI,BUI,RUI,CUI}_RECOVERED to XFS_LI_RECOVERED so that we track recovery status in the log item, then get rid of the now unused flags fields in each of those log item types.

* xfs: refactor recovered RUI log item playbackDarrick J. Wong2020-05-081-3/+0
| | | | | | | | | | Move the code that processes the log items created from the recovered log items into the per-item source code files and use dispatch functions to call them. No functional changes.

* xfs: refactor log recovery RUI item dispatch for pass2 commit functionsDarrick J. Wong2020-05-081-4/+0
| | | | | | | | | | | Move the rmap update intent and intent-done pass2 commit code into the per-item source code files and use dispatch functions to call them. We do these one at a time because there's a lot of code to move. No functional changes. Signed-off-by: Darrick J.

* 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: create rmap update intent log itemsDarrick J. Wong2016-08-031-0/+100
Create rmap update intent/done log items to record redo information in the log. Because we need to roll transactions between updating the bmbt mapping and updating the reverse mapping, we also have to track the status of the metadata updates that will be recorded in the post-roll transactions, just in case we crash before committing the final transaction. This mechanism enables log recovery to finish what was already started. Signed-off-by: Darrick J.
