The mm-of-the-moment snapshot 2022-02-11-15-07 has been uploaded to

   https://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

https://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
https://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory https://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm



This mmotm tree contains the following patches against 5.17-rc3:

The mm-of-the-moment snapshot 2022-02-11-15-07 has been uploaded to

   https://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

https://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
https://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory https://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm

Yes, TRACE_BRANCH_PROFILING and PROFILE_ALL_BRANCHES are fundamentally
broken and I have no intention of trying to fix them.

The moment we pull PTI into noinstr C code this will result in insta
boot fail.

Actually, I don't think anyone has every used the "tracers" for this, and I
will be happy to get rid of it:

void ftrace_likely_update(struct ftrace_likely_data *f, int val,
			  int expect, int is_constant)
{
	unsigned long flags = user_access_save();

	/* A constant is always correct */
	if (is_constant) {
		f->constant++;
		val = expect;
	}


------8<------
	/*
	 * I would love to have a trace point here instead, but the
	 * trace point code is so inundated with unlikely and likely
	 * conditions that the recursive nightmare that exists is too
	 * much to try to get working. At least for now.
	 */
	trace_likely_condition(f, val, expect);
----->8-------

	/* FIXME: Make this atomic! */
	if (val == expect)
		f->data.correct++;
	else
		f->data.incorrect++;

	user_access_restore(flags);
}
EXPORT_SYMBOL(ftrace_likely_update);

The above with the cut lines I added.

I still use the likely and unlikely counters. Would it be possible to mark
that function as "noinstr" and still record them (I don't care if there's
races where we miss a few or add a few too many). But they have been really
affective in finding bad locations of likely and unlikely callers.

As I said. I have no problem with removing the trace portion of that code.
It was more of an academic exercise than a useful one, but the counters
are still very useful to have.
