Bug Description
On a BTRFS volume with a lot of subvolumes, I get sporadic segfaults on "btrfs subvolume list", about 1/3 of the time. This is on Ubuntu 20.04.
linux-image-
On #btrfs on freenode, it was pointed out that 5.4.0-52.57 seems to have a regression but not the fix for it committed. To quote from the IRC message:
> 5.4.0-52.57 has a regression (a48b73eca4ce btrfs: fix potential deadlock in the search ioctl) and not the fix (1c78544eaa46 btrfs: fix wrong address when faulting in pages in the search ioctl)
