Cover letter [PATCH v2 0/4 for stable 6.1] btrfs: some directory fixes for stable 6.1

From: Filipe Manana <[email protected]>

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/[email protected]/

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
