The 5.2 kernel has been released

Linus Torvalds has released the 5.2 kernel.He originally planned for an rc8 this week, rather than 5.2, due to his travel schedule, but was pleasantly surprised at how calm things have been. "So despite a fairly late core revert, I don't see any real reason for another week of rc, and so we have a v5.2 with the normal releasetiming."Some of the more significant changes in 5.2 area new CLONE_PIDFD flag to clone() to obtain a pidfd for thenew process,a significant BPF verifier performance improvement that allows the maximumsize of a BPF program to be raised to 1 million instructions,a BPF hook to manage sysctl knobs,a new set of system calls for filesystemmounting,case-insensitive lookups for the ext4filesystem,a process freezer for version-2 control groups,pressure-stall monitors,and, of course, a vast number of fixes.See the KernelNewbies 5.2page for a lot more details.
