Reading the man page for io_uring_setup (from man/io_uring_setup.2), there is a reference to a flag named IORING_FEAT_ENTER_EXT_ARG.
However, io_uring.h defines IORING_ENTER_EXT_ARG and IORING_FEAT_EXT_ARG, but nothing with both FEAT and ENTER.
It's a minor issue since it's fairly obvious it should be IORING_FEAT_EXT_ARG, but it tripped me up for a few minutes.
