The 6.15 kernel has been released
Linus has https://lwn.net/Articles/1022493/
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 https://lwn.net/Articles/1012490/
to make
checkpoint/restore operations more reliable, the https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6092c5016005
to read status information from a pidfd after the process in question has
been reaped, the https://lwn.net/Articles/992991/
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, https://lwn.net/Articles/1011366/
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.
