Patch series "initramfs: "crc" cpio format and INITRAMFS_PRESERVE_MTIME", v7.
This patchset does some minor initramfs refactoring and allows cpio entry
mtime preservation to be disabled via a new Kconfig
INITRAMFS_PRESERVE_MTIME option.
Patches 4/6 to 6/6 implement support for creation and extraction of "crc"
cpio archives, which carry file data checksums. Basic tests for this
functionality can be found at https://github.com/rapido-linux/rapido/pull/163
This patch (of 6):
do_header() is called for each cpio entry and fails if the first six bytes
don't match "newc" magic. The magic check includes a special case error
message if POSIX.1 ASCII (cpio -H odc) magic is detected. This special
case POSIX.1 check can be nested under the "newc" mismatch code path to
avoid calling memcmp() twice in a non-error case.

When a process exits, /proc/${pid}, and /proc/${pid}/net dentries are
flushed. However some leaf dentries like /proc/${pid}/net/arp_cache
aren't. That's because respective PDEs have proc_misc_d_revalidate() hook
which returns 1 and leaves dentries/inodes in the LRU.
Force revalidation/lookup on everything under /proc/${pid}/net by
inheriting proc_net_dentry_ops.

sbi->s_firstinodezone is initialized to 2 and sbi->s_firstdatazone is read
from sbd. There's no guarantee that sbi->s_firstdatazone must bigger than
sbi->s_firstinodezone. If sbi->s_firstdatazone less than 2, the
filesystem can still be mounted unexpetly. At this point, sbi->s_ninodes
flip to very large value and this filesystem is broken. We can observe
this by executing 'df' command. When we execute, we will get an error
message:

The task exit struct needs some crucial information to be able to provide
an enhanced version of process and thread accounting. This change
provides:
1. ac_tgid in additon to ac_pid
2. thread group execution walltime in ac_tgetime
3. flag AGROUP in ac_flag to indicate the last task
in a thread group / process
4. device ID and inode of task's /proc/self/exe in
ac_exe_dev and ac_exe_inode
5. tools/accounting/procacct as demonstrator
When a task exits, taskstats are reported to userspace including the
task's pid and ppid, but without the id of the thread group this task is
part of. Without the tgid, the stats of single tasks cannot be correlated
to each other as a thread group (process).
The taskstats documentation suggests that on process exit a data set
consisting of accumulated stats for the whole group is produced. But such
an additional set of stats is only produced for actually multithreaded
processes, not groups that had only one thread, and also those stats only
contain data about delay accounting and not the more basic information
about CPU and memory resource usage. Adding the AGROUP flag to be set
when the last task of a group exited enables determination of process end
also for single-threaded processes.
My applicaton basically does enhanced process accounting with summed
cputime, biggest maxrss, tasks per process. The data is not available
with the traditional BSD process accounting (which is not designed to be
extensible) and the taskstats interface allows more efficient on-the-fly
grouping and summing of the stats, anyway, without intermediate disk
writes.
Furthermore, I do carry statistics on which exact program binary is used
how often with associated resources, getting a picture on how important
which parts of a collection of installed scientific software in different
versions are, and how well they put load on the machine. This is enabled
by providing information on /proc/self/exe for each task. I assume the
two 64-bit fields for device ID and inode are more appropriate than the
possibly large resolved path to keep the data volume down.
Add the tgid to the stats to complete task identification, the flag AGROUP
to mark the last task of a group, the group wallclock time, and
inode-based identification of the associated executable file.
Add tools/accounting/procacct.c as a simplified fork of getdelays.c to
demonstrate process and thread accounting.

In order for end users to quickly react to new issues that come up in
production, it is proving useful to leverage the printk indexing system.
This printk index enables kernel developers to use calls to printk() with
changeable ad-hoc format strings (as they always have; no change of
expectations), while enabling end users to examine format strings to
detect changes.
Since end users are using regular expressions to match messages printed
through printk(), being able to detect changes in chosen format strings
from release to release provides a useful signal to review
printk()-matching regular expressions for any necessary updates.
So that detailed FAT messages are captured by this printk index, this
patch wraps fat_msg with a macro.

ep_poll() first calls ep_events_available() with no lock held and checks
if ep->rdllist is empty by list_empty_careful(), which reads
rdllist->prev. Thus all accesses to it need some protection to avoid
store/load-tearing.
Note INIT_LIST_HEAD_RCU() already has the annotation for both prev
and next.
Commit bf3b9f6372 ("epoll: Add busy poll support to epoll with socket
fds.") added the first lockless ep_events_available(), and commit
c5a282e963 ("fs/epoll: reduce the scope of wq lock in epoll_wait()")
made some ep_events_available() calls lockless and added single call under
a lock, finally commit e59d3c64cb ("epoll: eliminate unnecessary lock
for zero timeout") made the last ep_events_available() lockless.

Patch series "Fix data-races around epoll reported by KCSAN."
This series suppresses a false positive KCSAN's message and fixes a real
data-race.
This patch (of 2):
pipe_poll() runs locklessly and assigns 1 to poll_usage. Once poll_usage
is set to 1, it never changes in other places. However, concurrent writes
of a value trigger KCSAN, so let's make KCSAN happy.

Patch series "Convert vmcore to use an iov_iter", v5.
For some reason several people have been sending bad patches to fix
compiler warnings in vmcore recently. Here's how it should be done.
Compile-tested only on x86. As noted in the first patch, s390 should take
this conversion a bit further, but I'm not inclined to do that work
myself.
This patch (of 3):
Instead of passing in a 'buf' and 'userbuf' argument, pass in an iov_iter.
s390 needs more work to pass the iov_iter down further, or refactor, but
I'd be more comfortable if someone who can test on s390 did that work.
It's more convenient to convert the whole of read_from_oldmem() to take an
iov_iter at the same time, so rename it to read_from_oldmem_iter() and add
a temporary read_from_oldmem() wrapper that creates an iov_iter.

Patch series "rewrite error handling during mounting stage".
This patch (of 5):
After commit da5e7c8782 ("ocfs2: cleanup journal init and shutdown"),
journal init later than before, it makes NULL pointer access in free
routine.
Crash flow:
ocfs2_fill_super
+ ocfs2_mount_volume
| + ocfs2_dlm_init //fail & return, osb->journal is NULL.
| + ...
| + ocfs2_check_volume //no chance to init osb->journal
|
+ ...
+ ocfs2_dismount_volume
ocfs2_release_system_inodes
...
evict
...
ocfs2_clear_inode
ocfs2_checkpoint_inode
ocfs2_ci_fully_checkpointed
time_after(journal->j_trans_id, ci->ci_last_trans)
+ journal is empty, crash!
For fixing, there are three solutions:
1> Partly revert commit da5e7c8782
For avoiding kernel crash, this make sense for us. We only
concerned whether there has any non-system inode access before dlm
init. The answer is NO. And all journal replay/recovery handling
happen after dlm & journal init done. So this method is not graceful
but workable.
2> Add osb->journal check in free inode routine (eg ocfs2_clear_inode)
The fix code is special for mounting phase, but it will continue
working after mounting stage. In another word, this method adds
useless code in normal inode free flow.
3> Do directly free inode in mounting phase
This method is brutal/complex and may introduce unsafe code,
currently maintainer didn't like.
At last, we chose method <1> and did partly reverted job. We reverted
journal init codes, and kept cleanup codes flow.

"These fix up the ACPI processor driver after a change made during the
5.16 cycle that inadvertently broke falling back to shallower C-states
when C3 cannot be used.
Specifics:
- Make the ACPI processor driver avoid falling back to C3 type of
C-states when C3 cannot be requested (Ville Syrjälä)
- Revert a quirk that is not necessary any more after fixing the
underlying issue properly (Ville Syrjälä)"
