The case try to: - open a file for writing - submit a list with invalid opcodes to lio_listio in LIO_NOWAIT mode - check that lio_listio returns -1 The POSIX specification(IEEE Std 1003.1-2008) says（Line 40292）： The supported operations are LIO_READ, LIO_WRITE, and LIO_NOP But the spec doesn't say what should happen if the value it not one of the 3 operation codes. In Khem Raj's <raj.khem@gmail.com> opioion, "for aio_lio_opcode posix says "The supported operations are LIO_READ, LIO_WRITE, and LIO_NOP" but it does not say what should happen if the value it not one of the above so IMO its not a bug but falls into undefined behavior."
