Message

Remove some cycles in a couple of places for zc sends. Touches a bunch of
bits here and there but the main theme is adding additional set of callbacks
for slower path and move in there some optional features.

Pavel Begunkov (7):
  io_uring: move kbuf put out of generic tw complete
  io_uring/net: remove extra notif rsrc setup
  io_uring/net: preset notif tw handler
  io_uring/net: rename io_uring_tx_zerocopy_callback
  io_uring/net: inline io_notif_flush()
  io_uring: move zc reporting from the hot path
  io_uring/net: move mm accounting to a slower path
