Linux 5.1

[Linus Torvalds]

So it's a bit later in the day than I usually do this, just because I
was waffling about the release. Partly because I got some small pull
requests today, but mostly just because I wasn't looking forward to
the timing of this upcoming 5.2 merge window.

But the last-minute pull requests really weren't big enough to justify
delaying things over, and hopefully the merge window timing won't be
all that painful either. I just happen to have the college graduation
of my oldest happen right smack dab in the middle of the upcoming
merge window, so I might be effectively offline for a few days there.
If worst comes to worst, I'll extend it to make it all work, but I
don't think it will be needed.

Anyway, on to 5.1 itself. The past week has been pretty calm, and the
final patch from rc6 is not all that big. The shortlog is appended,
but it's small changes all over. Networking, filesystem code, drivers,
tooling, arch updates. Nothing particularly odd stands out.

Of course, the shortlog below is just for that final calm week. On the
whole, 5.1 looks very normal with just over 13k commits (plus another
1k+ if you count merges). Which is pretty much our normal size these
days. No way to boil that down to a sane shortlog, with work all over.

Go out and test,

                Linus
