Subject: [PATCH v5 1/3] io_uring: use an enumeration for io_uring_register(2) opcodes
Date: Thu, 27 Aug 2020 15:40:42 +0200 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
The enumeration allows us to keep track of the last
io_uring_register(2) opcode available.
Behaviour and opcodes names don't change.
Reviewed-by: Kees Cook <[email protected]>
Signed-off-by: Stefano Garzarella <[email protected]>

v5:
- explicitly assign enum values since this is UAPI [Kees]
