Subject: [PATCH v3 0/6] add persistent submission state
Date: Sat,  1 Feb 2020 01:15:49 +0300	[thread overview]
Message-ID: <[email protected]> (raw)

Apart from unrelated first patch, this persues two goals:

1. start preparing io_uring to move resources handling into
opcode specific functions

2. make the first step towards long-standing optimisation ideas

Basically, it makes struct io_submit_state embedded into ctx, so
easily accessible and persistent, and then plays a bit around that.

v2: rebase
v3: drop the mm-related patch and rebase

Pavel Begunkov (6):
  io_uring: always pass non-null io_submit_state
  io_uring: place io_submit_state into ctx
  io_uring: move ring_fd into io_submit_state
  io_uring: move *link into io_submit_state
  io_uring: persistent req bulk allocation cache
  io_uring: optimise req bulk allocation cache
