The 6.15 kernel has been released

Date:
Mon, 26 May 2025 03:44:19 +0000

Description:
Linus has released the 6.15 kernel, as
expected. So this was delayed by a couple of hours because of a last-minute
	bug report resulting in one new feature being disabled at the
	eleventh hour, but 6.15 is out there now. Significant changes in 6.15 
include smarter timer-ID assignment to make
checkpoint/restore operations more reliable, the ability to read status 
information from a pidfd after the process in question has
been reaped, the PIDFD_SELF special pidfd value, nested
ID-mapped mounts , zero-copy network-data reception via io_uring, The ability
to read epoll events via io_uring, resilient
queued spinlocks for BPF programs, guard-page enhancements allowing them to be
placed in file-backed memory areas and for user space to detect their
presence, the once-controversial fwctl
subsystem , the optional sealing of some
system mappings , and much more. See the LWN merge-window summaries ( part1 , 
part2 ) and the in-progress KernelNewbies 6.15 page for
more information.
