Subject: [PATCHSET v3 0/4] Cleanup and improve MSG_RING performance
Date: Mon, 1 Apr 2024 11:56:25 -0600 [thread overview]
Message-ID: <20240401175757.1054072-1-axboe@kernel.dk> (raw)
Hi,
Hi,
MSG_RING rolls its own task_work handling, which there's really no need
for. Rather, it should use the generic io_uring infrastructure for this.
Add a helper for remote execution, and switch over MSG_RING to use it.
This both cleans up the code, and improves performance of this opcode
considerably.
