Subject: [PATCHSET v2 0/4] Add support for shared io-wq backends
Date: Fri, 24 Jan 2020 14:31:37 -0700 [thread overview]
Message-ID: <20200124213141.22108-1-axboe@kernel.dk> (raw)
Here's v2 of the shared wq backend patchset. A few minor changes in terms
of id validation, and a switch to using idr and also utilizing it for
lookups.
Changes since v1:
- Use idr instead of ida, and use it for lookups too
- Rename IORING_SETUP_SHARED to IORING_SETUP_ATTACH_WQ
- Don't allow id specified without IORING_SETUP_ATTACH_WQ
- Use id=0 if we run out of idr space instead of failing
- id==0 is not allowed for attach
