[GIT,PULL] io_uring updates for 6.9-rc1

Hi Linus, Here are the io_uring changes queued for the 6.9 kernel release. This pull request contains: - Make running of task_work internal loops more fair, and unify how the different methods deal with them (me) - Support for per-ring NAPI. The two minor networking patches are in a shared branch with netdev. (Stefan) - Add support for truncate (Tony) - Export SQPOLL utilization stats (Xiaobing) - Multishot fixes (Pavel) - Fix for a race in manipulating the request flags via poll (Pavel) - Cleanup the multishot checking by making it generic, moving it out of opcode handlers (Pavel) - Various tweaks and cleanups (me, Kunwu, Alexander) Please pull!
