[$] The rest of the 6.9 merge window

The 6.9-rc1
kernel prepatch was released on March 24, closing the merge window for
this development cycle. By that time, 12,435 non-merge changesets had been
merged into the mainline, making for a less-busy merge window than the last
couple of kernel releases (but similar to the 12,492 seen for 6.5). Well
over 7,000 of those changes were merged after the first-half merge-window summary was
written, meaning that the latter part of the merge window brought many more
interesting changes.
