Subject: [PATCHSET v3 0/4] Cleanup and improve MSG_RING performance
Date: Mon,  1 Apr 2024 11:56:25 -0600	[thread overview]
Message-ID: <[email protected]> (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.

 io_uring/io_uring.c | 30 ++++++++++++++++------
 io_uring/io_uring.h |  2 ++
 io_uring/msg_ring.c | 62 +++++++++++++++++++++------------------------
 3 files changed, 53 insertions(+), 41 deletions(-)

Changes since v2:
- Ensure fd install locking is correct
