[$] The first half of the 5.2 merge window

When he released the 5.1 kernel, Linus
Torvalds noted that he had a family event happening in the middle of the
5.2 merge window and that he would be offline for a few days in the middle.
He appears to be trying to make up for lost time before it happens: over
8,300 non-merge changesets have found their way into the mainline in the
first four days. As always, there is a wide
variety of work happening all over the kernel tree.
