Subject: [RFC 00/11] dynamic buffers + rsrc tagging
Date: Fri, 23 Apr 2021 01:19:17 +0100	[thread overview]
Message-ID: <[email protected]> (raw)

1) support dynamic managment for registered buffers, including
update.

2) add new IORING_REGISTER* for rsrc register and rsrc update,
which are just dispatch files/buffers to right callbacks. Needed
because old ones not nicely extendible. The drawback --
restrictions not supporting it with fine granularity.

3) Do rsrc tagging, with tag=0 ingnoring CQE posting.
Doesn't post CQEs on unregister, but can easily be changed

One more thing to discuss is 9/11

Bijan Mottahedeh (1):
  io_uring: implement fixed buffers registration similar to fixed files

Pavel Begunkov (10):
  io_uring: move __io_sqe_files_unregister
  io_uring: return back rsrc data free helper
  io_uring: decouple CQE filling from requests
  io_uring: preparation for rsrc tagging
  io_uring: add generic path for rsrc update
  io_uring: enumerate dynamic resources
  io_uring: add IORING_REGISTER_RSRC
  io_uring: add generic rsrc update with tags
  io_uring: prepare fixed rw for dynanic buffers
  io_uring: add full-fledged dynamic buffers support
