The mm-of-the-moment snapshot 2020-04-17-20-35 has been uploaded to
http://www.ozlabs.org/~akpm/mmotm/
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.
https://github.com/hnaz/linux-mm
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 also available at
https://github.com/hnaz/linux-mm
This mmotm tree contains the following patches against 5.7-rc1:

Thanks. Seems that file was missed.
Also, this code jumps through horrifying hoops in order to initialize
locals at their definition site. But the code looks so much better if
we Just Don't Do That!

I think the code would look even better if things just Had The Right Type!
struct squashfs_sb_info {
...
- struct squashfs_stream *stream;
+ union {
+ struct squashfs_stream *stream;
+ struct squashfs_stream __percpu *percpu_stream;
+ };
int squashfs_decompress(struct squashfs_sb_info *msblk, struct bio *bio,
int offset, int length, struct squashfs_page_actor *output)
{
struct squashfs_stream *stream = get_cpu_ptr(msblk->percpu_stream);
int res = msblk->decompressor->decompress(msblk, stream->stream, bh, b,
offset, length, output);
...
As an aside, that calling convention could do with putting some of the
arguments into a struct so the CPU spends less time shuffling arguments
from one register to another.
