xfs: convert to SPDX license tags

2018-06-06T21:17:53Z

Remove the verbose license text from XFS files and replace them with SPDX tags. 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 Reviewed-by: Darrick J.

xfs: fix xfs_rtalloc_rec units

2018-06-01T16:00:16Z

All the realtime allocation functions deal with space on the rtdev in units of realtime extents. However, struct xfs_rtalloc_rec confusingly uses the word 'block' in the name, even though they're really extents. Fix the naming problem and fix all the unit handling problems in the two existing users. Signed-off-by: Darrick J. Wong Reviewed-by: Allison Henderson Reviewed-by: Bill O'Donnell

xfs: cross-reference the realtime bitmap

2018-01-18T05:00:46Z

While we're scrubbing various btrees, cross-reference the records with the other metadata. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner

xfs: create block pointer check functions

2017-10-26T22:38:23Z

Create some helper functions to check that a block pointer points within the filesystem (or AG) and doesn't point at static metadata. We will use this for scrub. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner

xfs: export various function for the online scrubber

2017-06-19T21:11:34Z

Export various internal functions so that the online scrubber can use them to check the state of metadata. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: add a couple of queries to iterate free extents in the rtbitmap

2017-04-03T22:18:17Z

Add _query_range and _query_all functions to the realtime bitmap allocator. These two functions are similar in usage to the btree functions with the same name and will be used for getfsmap and scrub. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: simplify xfs_rtallocate_extent

2017-02-18T00:52:52Z

We can deduce the allocation type from the bno argument, and do the return without prod much simpler internally. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong [darrick: fix the macro for the non-rt build] Signed-off-by: Darrick J. Wong

xfs: make several functions static

2016-06-01T07:38:15Z

Al Viro noticed that xfs_lock_inodes should be static, and that led to ... a few more. These are just the easy ones, others require moving functions higher in source files, so that's not done here to keep this review simple.

xfs: combine xfs_rtmodify_summary and xfs_rtget_summary

2014-09-09T01:58:42Z

xfs_rtmodify_summary and xfs_rtget_summary are almost identical; fold them into xfs_rtmodify_summary_int(), with wrappers for each of the original calls. The _int function modifies if a delta is passed, and returns a summary pointer if *sum is passed. Signed-off-by: Eric Sandeen Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: global error sign conversion

2014-06-25T04:58:08Z

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
