Here follows the backport of some directory related fixes for the stable
6.1 tree. I tested these on top of 6.1.75.

These were recently requested by a user for 5.15 stable:

   https://lore.kernel.org/linux-btrfs/20240124225522.GA2614102@lxhi-087/

This request is to backport the same patches to 6.1, while the request
for 5.15 stabe is at:

   https://lore.kernel.org/linux-btrfs/cover.1706183427.git.fdmanana@suse.com/

V2: Added missing stashes changes to fix compilation for patch 1/4.

Filipe Manana (4):
  btrfs: fix infinite directory reads
  btrfs: set last dir index to the current last index when opening dir
  btrfs: refresh dir last index during a rewinddir(3) call
  btrfs: fix race between reading a directory and adding entries to it
