* io_uring: use tw for putting rsrcPavel Begunkov2022-12-071-0/+1
| | | | | | | | | Use task_work for completing rsrc removals, it'll be needed later for spinlock optimisations.

* io_uring: remove FFS_SCMPavel Begunkov2022-10-171-4/+0
| | | | | | | | | | | THe lifetime of SCM'ed files is bound to ring_sock, which is destroyed strictly after we're done with registered file tables. This means there is no need for the FFS_SCM hack, which was not available on 32-bit builds anyway.

| | | | | | | | | | | This reverts commit 4379d5f15b3fd4224c37841029178aa8082a242e. We removed notification flushing, also cleanup uapi preparation changes to not pollute it.

* io_uring/net: make page accounting more consistentPavel Begunkov2022-07-251-0/+9
| | | | | | | | | Make network page accounting more consistent with how buffer registration is working, i.e. account all memory to ctx->user.

* io_uring: rename IORING_OP_FILES_UPDATEPavel Begunkov2022-07-251-2/+2
| | | | | | | | | | IORING_OP_FILES_UPDATE will be a more generic opcode serving different resource types, rename it into IORING_OP_RSRC_UPDATE and add subtype handling.

* io_uring: add rsrc referencing for notifiersPavel Begunkov2022-07-251-3/+9
| | | | | | | | | | | In preparation to zerocopy sends with fixed buffers make notifiers to reference the rsrc node to protect the used fixed buffers. We can't just grab it for a send request as notifiers can likely outlive requests that used it.

* io_uring: move a few private types to local headersJens Axboe2022-07-251-0/+8
| | | | | | | | | | | | Commit 3a3d47fa9cfd ("io_uring: make io_uring_types.h public") moved a bunch of io_uring types to a kernel wide header, so we could make tracing a bit saner rather than pass in a ton of arguments. However, there are a few types in there that are not really needed to be system wide. Move the cancel data and mapped buffers back to the appropriate io_uring local headers.
