xfs: convert to SPDX license tags 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 <dchinner@redhat.com> Reviewed-by: Darrick J.

xfs: split out symlink code into it's own file. The symlink code is about to get more complicated when CRCs are added for remote symlink blocks. The symlink management code is mostly self contained, so move it to it's own files so that all the new code and the existing symlink code will not be intermingled with other unrelated code.

xfs: support idmapped mounts Enable idmapped mounts for xfs. This basically just means passing down the user_namespace argument from the VFS methods down to where it is passed to the relevant helpers. Note that full-filesystem bulkstat is not supported from inside idmapped mounts as it is an administrative operation that acts on the whole file system. The limitation is not applied to the bulkstat single operation that just operates on a single inode.

xfs: push down inactive transaction mgmt for remote symlinks Push down the transaction management for remote symlinks from xfs_inactive() down to xfs_inactive_symlink_rmt(). The latter is cleaned up to avoid transaction management intended for the calling context (i.e., trans duplication, reservation, item attachment).
