Hi Linus,
Also a collection of later fixes and additions, that weren't quite ready
for pushing out with the initial pull request. This pull request
contains:
- Fix potential use-after-free of shadow requests (Jackie)
- Fix potential OOM crash in request allocation (Jackie)
- kmalloc+memcpy -> kmemdup cleanup (Jackie)
- Fix poll crash regression (me)
- Fix SQ thread not being nice and giving up CPU for !PREEMPT (me)
- Add support for timeouts, making it easier to do epoll_wait()
conversions, for instance (me)
- Ensure io_uring works without f_ops->read_iter() and
f_ops->write_iter() (me)
Please pull!
