Correct some inaccurate and badly formatted comments.
config_subdisk: If our drive is down, ensure that the subdisk is
crashed. Previously it was possible for the subdisk
to be up when the drive was down.
Change the way the plex lock mutexes work. Previously they were part
of the struct plex, which tore apart the mutex linked lists when the
plex table was expanded. Now we maintain a pool of mutexes (currently
32) to be shared by all plexes. This is still a lot better than the
splhigh() method used in other architectures.
update_volume_config: Remove redundant diskconfig parameter.
