mmotm-readme.txt says

README for mm-of-the-moment:

http://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
http://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.

http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/



The directory http://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 available at

	http://git.cmpxchg.org/cgit.cgi/linux-mmots.git/

and use of this tree is similar to
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/, described above.

mm-shrinker-make-shrinker-not-depend-on-memcg-kmem-fix.patch fixes
the compile-time error when memcg_expand_shrinker_maps() is not
declared, but now we get a linker error instead because the
function is still not built into the kernel:

mm/vmscan.o: In function `prealloc_shrinker':
vmscan.c:(.text+0x328): undefined reference to `memcg_expand_shrinker_maps'

Sorry for chiming in late, I just came back from vacation.

The below patch should fix the issue, which is for linux-next
2019-07-08 on top of Andrew's fix. And, this patch fixed the redundant
#ifdef CONFIG_MEMCG problem pointed out by Randy. Copied Randy too.
