Pavel Begunkov d34b1b0b67 io_uring: use tw for putting rsrc
Use task_work for completing rsrc removals, it'll be needed later for
spinlock optimisations.

Pavel Begunkov 38eddb2c75 io_uring: remove FFS_SCM
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.

We removed notification flushing, also cleanup uapi preparation changes
to not pollute it.

Pavel Begunkov 6a9ce66f4d io_uring/net: make page accounting more consistent
Make network page accounting more consistent with how buffer
registration is working, i.e. account all memory to ctx->user.

Pavel Begunkov 4379d5f15b io_uring: rename IORING_OP_FILES_UPDATE
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.

Pavel Begunkov 68ef5578ef io_uring: add rsrc referencing for notifiers
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.

Jens Axboe ad163a7e25 io_uring: move a few private types to local headers
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.
