I really don't think that spamming dmesg every time a filesystem is
frozen or thawed is a good idea. This happens a *lot* when systems
are using snapshots, and for the most part nobody cares about
freeze/thaw cycles because they almost always work just fine.
I'd think that /proc/self/mounts would be a much better place to
indicate that the fs is frozen. After all, that's where we tell
people whether the filesystem is ro or rw, and frozen is just
a temporary, non-invasive ro state...
Cheers,
Dave.
