[PATCH v2 0/2] io_uring/io-wq: respect cgroup cpusets

[Felix Moessbauer]

Hi,

this series continues the affinity cleanup work started in
io_uring/sqpoll. It has been successfully tested against the liburing
testsuite (make runtests), liburing @ caae94903d2e201.

The test wq-aff.t succeeds if at least cpu 0,1 are in
the set and fails otherwise. This is expected, as the test wants
to pin on these cpus. I'll send a patch for liburing to skip that test
in case this pre-condition is not met.

Changes since v1:

- rework commit messages (don't use ambient cpus, wq threads are no
  pollers)
- no functional changes

Best regards,
Felix Moessbauer

  io_uring/io-wq: do not allow pinning outside of cpuset
  io_uring/io-wq: limit io poller cpuset to ambient one
