Title:
Doing multiple squashfs (and other loop?) mounts in parallel breaks
Status in linux package in Ubuntu:
Confirmed
Bug description:
On a system running a 5.2 kernel, doing a large number of mounts of
squashfs filesystems in parallel results in the mounts getting out of
sync with their backing devices.
To reproduce,
https://paste.ubuntu.com/p/VCpzGxvy6h/
this breaks people with ~40 snaps (easily achievable given snapd
leaves up to 3 previous revisions of snaps mounted at any given time,
so a person with ~13 snaps that get updated often will hit this
number).
