Kent Overstreet 9d86178782 bcachefs: bch2_inode_or_descendents_is_open() ...

fsck can now correctly check if inodes in interior snapshot nodes are
open/in use.

- Tweak the vfs inode rhashtable so that the subvolume ID isn't hashed,
  meaning inums in different subvolumes will hash to the same slot. Note
  that this is a hack, and will cause problems if anyone ever has the
  same file in many different snapshots open all at the same time.

- Then check if any of those subvolumes is a descendent of the snapshot
  ID being checked
