Subject: [PATCHSET next 0/4] Allow cancelation based on fd
Date: Thu, 14 Apr 2022 14:24:15 -0600 [thread overview]
Message-ID: <20220414202419.201614-1-axboe@kernel.dk> (raw)
Hi,
We currently only support looking up and canceling requests based on
the user_data of the original request. Sometimes it can be useful to
instead key off the fd used in the original request, eg if a socket
goes away.
Patch 1 is just a cleanup spotted while doing this, 2+3 are prep patches,
and patch 4 then finally is the meat of it.
Adds IORING_ASYNC_CANCEL_FD as a IORING_OP_ASYNC_CANCEL request flag,
which tells the kernel that we're looking up by fd rather than user_data.
