[$] The rest of the 5.6 merge window

Linus Torvalds released the 5.6-rc1prepatch and closed the merge window on February 9; at that point, 10,780 non-mergechangesets had been pulled into the mainline repository for 5.6. That issubstantially less than recent development cycles (14,350 for 5.5, 14,619for 5.4), but is similar to what was going on at this time last year(10,843 for 5.0-rc1 in January 2019). About 6,000 of those changes werepulled since the first 5.6 merge-windowarticle was written; read on for what was included in those changes.
