Hi Linus,
Mostly fixes for regressions in this cycle, but also a few fixes that
predate this release. The odd one out is a tweak to the direct files
added in this release, where attempting to reuse a slot is allowed
instead of needing an explicit removal of that slot first. It's a
considerable improvement in usability to that API, hence I'm sending it
for -rc2.
- io-wq race fix and cleanup (Hao)
- loop_rw_iter() type fix
- SQPOLL max worker race fix
- Allow poll arm for O_NONBLOCK files, fixing a case where it's
impossible to properly use io_uring if you cannot modify the file
flags
- Allow direct open to simply reuse a slot, instead of needing it
explicitly removed first (Pavel)
- Fix a case where we missed signal mask restoring in cqring_wait, if we
hit -EFAULT (Xiaoguang)
Please pull!
