Hi Linus,
Followup pull request for io_uring for the 6.14 merge window. This pull
request contains:
- Series cleaning up the alloc cache changes from this merge window, and
then another series on top making it better yet. This also solves an
issue with KASAN_EXTRA_INFO, by making io_uring resilient to KASAN
using parts of the freed struct for storage.
- Cleanups and simplications to buffer cloning and io resource node
management.
- Fix an issue introduced in this merge window where READ/WRITE_ONCE was
used on an atomic_t, which made some archs complain.
- Fix for an errant connect retry when the socket has been shut down.
- Fix for multishot and provided buffers.
Please pull!
