Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't take dev_replace rwsem on task already holding it
Running fstests btrfs/011 with MKFS_OPTIONS="-O rst" to force the usage of
the RAID stripe-tree, we get the following splat from lockdep:
BTRFS info (device sdd): dev_replace from /dev/sdd (devid 1) to /dev/sdb started
============================================
WARNING: possible recursive locking detected
6.11.0-rc3-btrfs-for-next #599 Not tainted
--------------------------------------------
btrfs/2326 is trying to acquire lock:

but task is already holding lock:
ffff88810f215c98 (&fs_info->dev_replace.rwsem){++++}-{3:3}, at: btrfs_map_block+0x39f/0x2250
other info that might help us debug this:
Possible unsafe locking scenario:
