Kernel prepatch 4.19-rc4; Linus taking a break

Linus has released 4.19-rc4 and made a setof announcements that should really be read in their entirety."I actually think that 4.19 is looking fairly good,things have gotten to the 'calm' period of the release cycle, and I'vetalked to Greg to ask him if he'd mind finishing up 4.19 for me, sothat I can take a break, and try to at least fix my own behavior."
