On a second thought, I think that size of log file should not exceed
the pstore buffer size in order to be read back later.  When total size
of log files becomes larger then the limit, the oldest file of same
type can be deleted. This way looks simpler to manage IMHO.

Also I think the pstore id should be managed by host device rather
than guest driver to handle splitted files properly.
