[$] The rest of the 6.3 merge window

Linus Torvalds released6.3-rc1 and closed the 6.3 merge window as expected on March 5.By that time, 12,717 non-merge commits (and 848 merges) had found theirway into the mainline kernel; nearly 7,000 of those commits came in after the first-half merge-window summary waswritten. The second half of the 6.3 merge window was thus a busy time,with quite a bit of new functionality landing in the mainline.
