Kernel prepatch 5.15-rc1
Linus has released 5.15-rc1 and closed the merge window for this development cycle.

So 5.15 isn't shaping up to be a particularly large release, at least in number of commits. At only just over 10k non-merge commits, this is in fact the smallest rc1 we have had in the 5.x series. We're usually hovering in the 12-14k commit range.

That said, counting commits isn't necessarily the best measure, and that might be particularly true this time around. We have a few new subsystems, with NTFSv3 and ksmbd standing out.
