Subject: [PATCHSET 0/3] Add REQ_F_CQE_SKIP support to io_uring zerocopy

This patchset allows for io_uring zerocopy to support REQ_F_CQE_SKIP,
skipping the normal completion notification, but not the zerocopy buffer
release notification.

This patchset also includes a test to test these changes, and a patch to
mini_liburing to enable io_uring_peek_cqe, which is needed for the test.

Oliver Crumrine (3):
  io_uring: Add REQ_F_CQE_SKIP support for io_uring zerocopy
  io_uring: Add io_uring_peek_cqe to mini_liburing
  io_uring: Support IOSQE_CQE_SKIP_SUCCESS in io_uring zerocopy test
