commit ef0ec1ad03119b8b46b035dad42bca7d6da7c2e5 upstream.
We should not be messing with req->file outside of core paths. Clearing
it makes msg_ring non reentrant, i.e. luckily io_msg_send_fd() fails the
request on failed io_double_lock_ctx() but clearly was originally
intended to do retries instead.

io_uring: add custom opcode hooks on fail2022-10-21T10:37:32+00:00Pavel Begunkovasml.silence@gmail.com2022-09-21T11:17:46+00:00urn:sha1:62e7adf96a3a8e7c6dac436e677af848f24a0493
commit a47b255e90395bdb481975ab3d9e96fcf8b3165f upstream.
Sometimes we have to do a little bit of a fixup on a request failuer in
io_req_complete_failed(). Add a callback in opdef for that.

io_uring: conditional ->async_data allocation2022-08-24T14:57:28+00:00Pavel Begunkovasml.silence@gmail.com2022-08-24T12:07:42+00:00urn:sha1:5916943943d19a854238d50d1fe2047467cbeb3c
There are opcodes that need ->async_data only in some cases and
allocation it unconditionally may hurt performance. Add an option to
opdef to make move the allocation part from the core io_uring to opcode
specific code.
Note, we can't just set opdef->async_size to zero because there are
other helpers that rely on it, e.g. io_alloc_async_data().

io_uring: move opcode table to opdef.c2022-07-25T00:39:12+00:00Jens Axboeaxboe@kernel.dk2022-06-15T22:27:42+00:00urn:sha1:d9b57aa3cfc792ccac6858376c017dbea6cb2872
We already have the declarations in opdef.h, move the rest into its own
file rather than in the main io_uring.c file.

io_uring: move poll handling into its own file2022-07-25T00:39:12+00:00Jens Axboeaxboe@kernel.dk2022-05-26T02:31:09+00:00urn:sha1:329061d3e2f9a0082a097e9558bd5497098586c6
Add a io_poll_issue() rather than export the general task_work locking
and io_issue_sqe(), and put the io_op_defs definition and structure into
a separate header file so that poll can use it.
