Create a new type (xfs_dqtype_t) to represent the type of an incore
dquot (user, group, project, or none). Rename the incore dquot's
dq_flags field to q_type.
This allows us to replace all the "uint type" arguments to the quota
functions with "xfs_dqtype_t type", to make it obvious when we're
passing a quota type argument into a function.

We're going to split up the incore dquot state flags from the ondisk
dquot flags (eventually renaming this "type") so start by renaming the
three flags and the bitmask that are going to participate in this.

Add counter fields to the incore dquot, and use that instead of the ones
in qcore. This eliminates a bunch of endian conversions and will
eventually allow us to remove qcore entirely.

Add a dquot id field to the incore dquot, and use that instead of the
one in qcore. This eliminates a bunch of endian conversions and will
eventually allow us to remove qcore entirely.
We also rearrange the start of xfs_dquot to remove padding holes, saving
8 bytes.

Scrubbing directories, quotas, and fs counters all involve iterating
some collection of metadata items. The per-item scrub functions for
these three are missing some of the components they need to be able to
check for a fatal signal and terminate early.
Per-item scrub functions need to call xchk_should_terminate to look for
fatal signals, and they need to check the scrub context's corruption
flag because there's no point in continuing a scan once we've decided
the data structure is bad. Add both of these where missing.

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.

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

}
/^ \*/ {
if (hdr > 0.0)

print $0

// {
if (hdr > 0.0) {

Refactor the quota scrubber to take the quotaofflock and grab the quota
inode in the setup function so that we can treat quota in the same
"scrub in the context of this inode" (i.e. sc->ip) manner as we treat
any other inode. We do have to drop the quota inode's ILOCK_EXCL to use
dqiterate, but since dquots have their own individual locks the ILOCK
wasn't helping us anyway.

There were ad-hoc checks for some scrub types but not others;
mark each scrub type with ... it's type, and use that to validate
the allowed and/or required input fields.
Moving these checks out of xfs_scrub_setup_ag_header makes it
a thin wrapper, so unwrap it in the process.

It's only used for tracepoints so it's relatively harmless,
but the offset is calculated incorrectly in xfs_scrub_quota_item.
qi_dqperchunk is the nr. of dquots per "chunk" which we have
conveniently *cough* defined to always be 1 FSB. Therefore
block_offset * qi_dqperchunk == first id in that chunk,
and so offset = id / qi_dqperchunk
id * dqperchunk is ... meaningless.
