bug#58598: [parted-devel] [PATCH]parted: acquire flock before modifying the device superblock

[John Gilmore]

Parted shouldn't lock itself (or systemd) out of concurrent access
to the same device.  But if there is a bug relating to concurrent
"formatting a filesystem and systemd", then why not get an flock
just for the duration of formatting a file system?  Formatting
is a write-only operation and there's no point in trying to do two
of them concurrently on the same file system.
