[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This cleans bits around iov remapping. The patches were initially
for-5.9, but if you want it for 5.10 let me know, I'll rebase.

Pavel Begunkov (4):
  io_uring: simplify io_rw_prep_async()
  io_uring: refactor io_req_map_rw()
  io_uring: fix ovelapped memcpy in io_req_map_rw()
  io_uring: kill extra user_bufs check
