[PATCH v2 1/3] io_uring: Create a helper to return the SQE size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Create a simple helper that returns the size of the SQE. The SQE could
have two size, depending of the flags.

If IO_URING_SETUP_SQE128 flag is set, then return a double SQE,
otherwise returns the sizeof of io_uring_sqe (64 bytes).
