Linus has released the 5.15 kernel after
another nine-week development cycle.

This release may have started out with some -Werror pain, but it
calmed down fairly quickly and on the whole 5.15 was fair small and
calm. Let’s hope for more of the same – without Werror issues this
time – for the upcoming merge window.


The code name for this release has been set to “Trick or Treat”.

Significant features in this release include:
the realtime
preemption locking code
,
descriptorless files for io_uring,
BPF timers,
the removal of mandatory file-locking support,
the ksmbd SMB filesystem server (but see this
article
),
printk() indexing,
the process_mrelease() system
call
,
The DAMON memory-management optimization
system,
the ntfs3 filesystem implementation,
and much more. See the
KernelNewbies 5.15 page
for more information.
