Subject: [PATCH liburing v2 0/5] liburing: add helpers to enable/disable eventfd notifications
Date: Wed, 20 May 2020 19:07:09 +0200	[thread overview]
Message-ID: <[email protected]> (raw)

This series is based on top of a new IORING_CQ_EVENTFD_DISABLED
flag available in the CQ ring flags.

I added io_uring_cq_eventfd_enabled() to get the status of eventfd
notifications, and io_uring_cq_eventfd_toggle() to disable/enabled
eventfd notifications.

I updated man pages and I added a eventfd-disable.c test case.

v1 -> v2:
  - renamed io_uring_cq_eventfd_toggle()
  - return EOPNOTSUPP only if we need to change the flag

Stefano Garzarella (5):
  Add CQ ring 'flags' field
  man/io_uring_setup.2: add 'flags' field in the struct
    io_cqring_offsets
  Add helpers to set and get eventfd notification status
  man/io_uring_register.2: add IORING_CQ_EVENTFD_DISABLED description
  Add test/eventfd-disable.c test case
