It's been a few years since we've sorted this thing, and the end result
is that we've added MAINTAINERS entries in the wrong order, and a number
of entries have their fields in non-canonical order too.
So roll this boulder up the hill one more time by re-running
./scripts/parse-maintainers.pl --order
on it.
This file ends up being fairly painful for merge conflicts even
normally, since unlike almost all other kernel files it's one of those
"everybody touches the same thing", and re-ordering all entries is only
going to make that worse. But the alternative is to never do it at all,
and just let it all rot..
The rc2 week is likely the quietest and least painful time to do this.

* tag 'gfs2-v6.3-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2:
gfs2: Don't deref jdesc in evict
On corrupt gfs2 file systems the evict code can try to reference the
journal descriptor structure, jdesc, after it has been freed and set to
NULL. The sequence of events is:
init_journal()
...
fail_jindex:
gfs2_jindex_free(sdp); <------frees journals, sets jdesc = NULL
if (gfs2_holder_initialized(&ji_gh))
gfs2_glock_dq_uninit(&ji_gh);
fail:
iput(sdp->sd_jindex); <--references jdesc in evict_linked_inode
evict()
gfs2_evict_inode()
evict_linked_inode()
ret = gfs2_trans_begin(sdp, 0, sdp->sd_jdesc->jd_blocks);
<------references the now freed/zeroed sd_jdesc pointer.
The call to gfs2_trans_begin is done because the truncate_inode_pages
call can cause gfs2 events that require a transaction, such as removing
journaled data (jdata) blocks from the journal.
This patch fixes the problem by adding a check for sdp->sd_jdesc to
function gfs2_evict_inode. In theory, this should only happen to corrupt
gfs2 file systems, when gfs2 detects the problem, reports it, then tries
to evict all the system inodes it has read in up to that point.

During an IGT GPU reset test we see again oops despite of
commit 0c8c901aaaebc9 (drm/sched: Check scheduler ready before calling
timeout handling).
It uses ready condition whether to call drm_sched_fault which unwind
the TDR leads to GPU reset.
However it looks the ready condition is overloaded with other meanings,
for example, for the following stack is related GPU reset :
0 gfx_v9_0_cp_gfx_start
1 gfx_v9_0_cp_gfx_resume
2 gfx_v9_0_cp_resume
3 gfx_v9_0_hw_init
4 gfx_v9_0_resume
5 amdgpu_device_ip_resume_phase2
does the following:
/* start the ring */
gfx_v9_0_cp_gfx_start(adev);
ring->sched.ready = true;
The same approach is for other ASICs as well :
gfx_v8_0_cp_gfx_resume
gfx_v10_0_kiq_resume, etc...
As a result, our GPU reset test causes GPU fault which calls unconditionally gfx_v9_0_fault
and then drm_sched_fault. However now it depends on whether the interrupt service routine
drm_sched_fault is executed after gfx_v9_0_cp_gfx_start is completed which sets the ready
field of the scheduler to true even for uninitialized schedulers and causes oops vs
no fault or when ISR drm_sched_fault is completed prior gfx_v9_0_cp_gfx_start and
NULL pointer dereference does not occur.
Use the field timeout_wq to prevent oops for uninitialized schedulers.
The field could be initialized by the work queue of resetting the domain.

When run the test in netns, it's not easy to get the tc stats via
tc_rule_handle_stats_get(). With the new netns parameter, we can get
stats from specific netns like
num=$(tc_rule_handle_stats_get "dev eth0 ingress" 101 ".packets" "-n ns")
