Hi,

Here's v3 of this patchset, it's looking pretty clean by now. For the
v2 posting, please look here:

https://lore.kernel.org/io-uring/[e-mail]/T/#ma92ca3d24796b56414c68e49213bf6455002eb06

This series can also be found here:

https://git.kernel.dk/cgit/linux/log/?h=io_uring-rsrc

with previous versions in .1, and .2 postfixes of that branch.

Changes since v2:
- Don't pass in pointer to index to io_rsrc_node_lookup()
- Add io_reset_rsrc_node() helper, which cleans up some of the "lookup
  old node, if it exists, and put it" logic in various spots.
- Get rid of 'rsrc' member in buf/file union, clear the right pointer
  when the specific resource is put
- Drop unused IORING_RSRC_INVALID type
- Drop unused 'index' argument for io_rsrc_node_alloc()
- Use rsrc_empty_node consistently
- Rebase on current for-6.13 + 6.12 fixes
