Subject: [PATCH net-next v4 24/27] io_uring: rename IORING_OP_FILES_UPDATE
Date: Thu, 7 Jul 2022 12:49:55 +0100 [thread overview]
Message-ID: <ab408ab3cd84dee1f797f2539c60d28aa5c4c418.1657194434.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
IORING_OP_FILES_UPDATE will be a more generic opcode serving different
resource types, rename it into IORING_OP_RSRC_UPDATE and add subtype
handling.
