The 5.15 kernel has been released
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.
