inline fn __io_uring_prep_poll_mask(poll_mask: u32) u32
[src]
Poll masks previously used to comprise of 16 bits in the flags union of a SQE, but were then extended to comprise of 32 bits in order to make room for additional option flags. To ensure that the correct bits of poll masks are consistently and properly read across multiple kernel versions, poll masks are enforced to be little-endian. https://www.spinics.net/lists/io-uring/msg02848.html
