MM of the moment has updated. It’s rebased on v5.16-rc7, adds 32 new patches to the queue, drops 11 patches from the queue, and modifies 100 existing patches. In total, 360 patches are in the queue.

Two more mm fixes have pull-requested to Linus Torvalds.

Linux 5.16-rc8 (Linus Torvalds)

As expected, unusual rc8 has made for 5.16. And also as expected, this is a quite tiny rc. Torvalds will release 5.16 next week. He also encourages subsystem maintainers to send pull request early if possible, because he will have a travel during the next merge window.

Below is the diffstat of the releases in the last two years.
