corruption of active mmapped files in btrfs snapshots
For quite a while, I''ve experienced oddities with snapshotted Firefox
_CACHE_00?_ files, whose checksums (and contents) would change after the
btrfs snapshot was taken, and would even change depending on how the
file was brought to memory (e.g., rsyncing it to backup storage vs
checking its md5sum before or after the rsync). This only affected
these cache files, so I didn''t give
