Subject: [RFC 00/11] dynamic buffers + rsrc tagging
Date: Fri, 23 Apr 2021 01:19:17 +0100 [thread overview]
Message-ID: <cover.1619128798.git.asml.silence@gmail.com> (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
