[$] The rest of the 6.15 merge window

Linus Torvalds released 6.15-rc1 and
closed the 6.15 merge window on April 6. By that time, 12,633
non-merge changesets had found their way into his repository; that is
substantially more than were merged during the entire 6.14
development cycle. Just under 6,000 of those changesets were merged after
the first-half merge-window summary was
written.
