[GIT PULL] io_uring fixes for 6.17-rc4

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Two fixes for the ring provided buffers in this pull request:

- Use the proper type for min_t() in getting the min of the leftover
  bytes and the buffer length.

- As good practice, use READ_ONCE() consistently for reading ring
  provided buffer lengths. Additionally, stop looping for incremental
  commits if a zero sized buffer is hit, as no further progress can be
  made at that point.

Please pull!
