I'm having a hard time telling which opcodes can use a fixed file. I assume all would?
I don't see 'read' explicitly saying it supports it, but it ran fine.
I'm able to open a file (normal call) and use IORING_OP_STATX with AT_EMPTY_PATH to get the file size.
When I try to use openat and use a fixed file it no longer works. Is this unsupported?
I don't see "sqe->flags |= IOSQE_FIXED_FILE;" in the statx test, I'm assuming if I don't see a test for it, it's likely not supported?
