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-rc2:

Thanks for pointing this out. The kernel test robot emailed me about it and I am working on fixing it for v2.
