Replace the two users of the ->data_unused_p dir ops method with a direct calculation using ->data_entry_offset, and clean them up a bit. xfs_dir2_sf_to_block already had an offset variable containing the value of ->data_entry_offset, which we are now reusing to make it clear that the initial freespace entry is at the same place that we later fill in the 1 entry, and in xfs_dir3_data_init the function is cleaned up a bit to keep the initialization of fields of a given structure close to each other, and to avoid a local variable.

The only user of the ->data_dot_entry_p and ->data_dotdot_entry_p methods is the xfs_dir2_sf_to_block function that builds block format directorys from a short form directory. It already uses pointer arithmetics with a offset variable to do so for the real entries in the directory, so switch the generation of the . and .. entries to the same scheme, and clean up some of the later pointer arithmetics to use bp->b_addr directly as well and avoid some casts.

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: NDave Chinner <dchinner@redhat.com> Reviewed-by: NDarrick J.

In xfs_dir2_data_use_free, we examine on-disk metadata and ASSERT if it doesn't make sense. Since a carefully crafted fuzzed image can cause the kernel to crash after blowing a bunch of assertions, let's move those checks into a validator function and rig everything up to return EFSCORRUPTED to userspace.
