[PATCH 0/9] Bijan's rsrc generalisation + prep parts

[Pavel Begunkov <asml.silence@gmail.com>]

I guess we can agree that generic rsrc handling is a good thing to have,
even if we have only files at the moment. This consists of related
patches from the Bijan's longer series, doesn't include sharing and
buffer bits. I suggest to merge it first. It's approx half of the all
changes.

Based on 5.12 with a few pathes from 5.11 cherry-pick to reduce merge
conflicts, because of merging/etc. may wait for a week or so for the
next rc before potentially being merged. This also addressed tricky
merge conflicts where it was applying and compiling well but still
buggy.

Bijan, for the changed patches I also dropped your signed-off, so
please reply if you're happy with the new versions so we can
add it back. There are change logs (e.g. [did so]) in commit messages
of those.

Mapping to the original v5 series:
1-5/9 (1-5/13 originally), mostly unchanged
6/9 -- my own prep
7/9 (7/13 originally), only file part
8/9 (10/13 originally), only file part
9/9 (11/13 before), unchanged

Bijan Mottahedeh (8):
  io_uring: rename file related variables to rsrc
  io_uring: generalize io_queue_rsrc_removal
  io_uring: separate ref_list from fixed_rsrc_data
  io_uring: add rsrc_ref locking routines
  io_uring: split alloc_fixed_file_ref_node
  io_uring: create common fixed_rsrc_ref_node handling routines
  io_uring: create common fixed_rsrc_data allocation routines
  io_uring: make percpu_ref_release names consistent

Pavel Begunkov (1):
  io_uring: split ref_node alloc and init
