From: Filipe Manana <fdmanana@suse.com>

Here follows the backport of some directory related fixes for the stable
5.15 tree. I tested these on top of 5.15.147.

These were recently requested at:

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
