In this round, we added a new mount option, "checkpoint_merge", which introduces
a kernel thread dealing with the f2fs checkpoints. Once we start to manage the
IO priority along with blk-cgroup, the checkpoint operation can be processed in
a lower priority under the process context. Since the checkpoint holds all the
filesystem operations, we give a higher priority to the checkpoint thread all
the time.
Enhancement:
- introduce gc_merge mount option to introduce a checkpoint thread
- improve to run discard thread efficiently
- allow modular compression algorithms
- expose # of overprivision segments to sysfs
- expose runtime compression stat to sysfs
Bug fix:
- fix OOB memory access by the node id lookup
- avoid touching checkpointed data in the checkpoint-disabled mode
- fix the resizing flow to avoid kernel panic and race conditions
- fix block allocation issues on pinned files
- address some swapfile issues
- fix hugtask problem and kernel panic during atomic write operations
- don't start checkpoint thread in RO
And, we've cleaned up some kernel coding style and build warnings. In addition,
we fixed some minor race conditions and error handling routines.

There are two TCC activation temeprature.
One is the default TCC activation temperature, also known as TJ_MAX.
Another one is the effective TCC activation temperature, which is the
subtraction of default TCC activation temperature and TCC offset.
The name of variable tcc_activation_temp might be misleading here.
Thus rename tcc_activation_temp to tj_max, and use tcc_default and
tcc_offset to calculate the effective TCC activation temperature.
No functional change in this patch.

For Atom CPUs that have core cstate deeper than C6,
MSR_CORE_C6_RESIDENCY actually returns the residency for both CC6 and
deeper Core cstates.
Thus, the real Core C6 residency should be the subtraction of

C-state pre-wake setting[1] is an optimization for some Intel CPUs to
be woken up from deep C-states in order to reduce latency. According to
the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting
accordingly.
Sample output from turbostat:
...

It was found that on Elkhart Lake the TSC frequency is driven by
a separate crystal-clock domain, which is different from the
BCLK domain which includes mperf. This has result in small different
speed thus inconsistence between TSC and the mperf, which caused the
Busy% to be higher than 100%. On this platform it seems that the mperf
runs faster than tsc when the CPU is 100% utilized:
delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds.
To align TSC with mperf, leverage the tsc_tweak mechanism introduced for
cores newer than Skylake, so that TSC and mperf would be calculated in
the same domain.

Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.
So this patch:
1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.
And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.
This patch combined the modification from Bingsong Si and
Bas Nieuwenhuizen and addd the MSR to the index system as alternative for
MSR_PKG_ENERGY_STATUS.

Use linux-perf to access the hardware instructions-retired counter.
This is necessary because the counter is not enabled by default,
and also the counter is prone to roll-over -- both of which
perf manages.
It is not necessary to use perf for the cycle counter,
because turbostat already needs to collect delta-aperf
to calcuate frequency.

This adds support to the remoteproc core for detaching Linux from a
running remoteproc, e.g. to reboot Linux while leaving the remoteproc
running, and it enable this support in the stm32 remoteproc driver.
It also introduces a property for memory carveouts to track if they are
iomem or system ram, to enable proper handling of the differences.
The imx_rproc received a number of fixes and improvements, in particular
support for attaching to already running remote processors and i.MX8MQ

The Qualcomm wcss driver gained support for starting and stopping the

Perl, as with most scripting languages, is fairly flexible in how /
where you can define things, and it will (for the most part) do what you
would expect it to do. This however can lead to situations, like with
ktest, where things get muddled over time.
This pushes the variable definitions back up to the top, followed by
functions, with the main script executables down at the bottom, INSTEAD
of being somewhat mish-mashed together in certain places. This mostly
has the advantage of making it more obvious where things are initially
defined, what functions are there, and ACTUALLY where the main script
starts executing, and should make this a little more approachable.

This is a followup to "ktest: Adding editor hints to improve
consistency" to actually adjust the existing indentation to match
the, now, expected pattern (first column 4 spaces, 2nd tab, 3rd
tab + 4 spaces, etc). This should, at least help, keep things
consistent going forward now.

Emacs and Vi(m) have different styles of dealing with perl syntax
which can lead to slightly inconsistent indentation, and makes the
code slightly harder to read. Emacs assumes a more perl recommended
standard of 4 spaces (1 column) or tab (two column) indentation.
Vi(m) tends to favor just normal spaces or tabs depending on what
was being used.
This gives the basic hinting to Emacs and Vim to do what is
expected to be basically consistent.
Emacs:
- Explicitly flip into perl mode, cperl would require
more adjustments
Vi(m):
- Set softtabs=4 which will flip it over to doing
indentation the way you would expect from Emacs

New feature:
The "func-no-repeats" option in tracefs/options directory. When set
the function tracer will detect if the current function being traced
is the same as the previous one, and instead of recording it, it will
keep track of the number of times that the function is repeated in a row.
And when another function is recorded, it will write a new event that
shows the function that repeated, the number of times it repeated and
the time stamp of when the last repeated function occurred.
Enhancements:
In order to implement the above "func-no-repeats" option, the ring
buffer timestamp can now give the accurate timestamp of the event
as it is being recorded, instead of having to record an absolute
timestamp for all events. This helps the histogram code which no longer
needs to waste ring buffer space.
New validation logic to make sure all trace events that access
dereferenced pointers do so in a safe way, and will warn otherwise.
Fixes:
No longer limit the PIDs of tasks that are recorded for "saved_cmdlines"
to PID_MAX_DEFAULT (32768), as systemd now allows for a much larger
range. This caused the mapping of PIDs to the task names to be dropped
for all tasks with a PID greater than 32768.
Change trace_clock_global() to never block. This caused a deadlock.
Clean ups:
Typos, prototype fixes, and removing of duplicate or unused code.
Better management of ftrace_page allocations.

Pull tracing updates from Steven Rostedt:
"New feature:
- A new "func-no-repeats" option in tracefs/options directory.
When set the function tracer will detect if the current function
being traced is the same as the previous one, and instead of
recording it, it will keep track of the number of times that the
function is repeated in a row. And when another function is
recorded, it will write a new event that shows the function that
repeated, the number of times it repeated and the time stamp of
when the last repeated function occurred.

mm/readahead.c/read_pages was quite a bit different back
when I put my open-coded readahead logic into orangefs_readpage.
It seemed to work as designed then, it is a trainwreck now.
This patch implements orangefs_readahead using new xarray
and readahead_expand features that have just been pulled and
removes all my open-coded readahead logic.
This patch results in an extreme read performance improvement,
these sample numbers are from my test VM:
Here's an example of what's upstream in
5.11.8-200.fc33.x86_64:
30+0 records in
30+0 records out
125829120 bytes (126 MB, 120 MiB) copied, 5.77943 s, 21.8 MB/s
And here's this version of orangefs_readahead on top of
5.12.0-rc4:
30+0 records in
30+0 records out
125829120 bytes (126 MB, 120 MiB) copied, 0.325919 s, 386 MB/s
There are four xfstest regressions with this patch. David Howells
and Matthew Wilcox have been helping me work with this code. One
of the regressions has gone away with the most recent version of
their code that I'm using. I hope this patch can be
pulled even though there are still a few regressions, and that
we can try to get them resolved during the RC period.
