Subject: [PATCHSET v2 for-next 0/2] Add direct descriptor ring passing
Date: Sat, 18 Jun 2022 19:59:20 -0600 [thread overview]
Message-ID: <20220619015922.1325241-1-axboe@kernel.dk> (raw)
Hi,
One of the things we currently cannot do with direct descriptors is pass
it to another application or ring. This adds support for doing so, through
the IORING_OP_MSG_RING ring-to-ring messaging opcode.
Changes since v1:
- Add IORING_MSG_RING_CQE_SKIP flag for IORING_OP_MSG_RING
- Expand commit message in patch 2
