Subject: [PATCHSET v3] Add direct descriptor ring passing
Date: Wed, 22 Jun 2022 17:16:09 -0600 [thread overview]
Message-ID: <20220622231611.178300-1-axboe@kernel.dk> (raw)
Hi,
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 v2:
- Add flag for controlling whether to post a CQE to the target ring or
not.
