Sorry, that was my mistake - this is true for regexes, but since LVM2 
filter regexes have an implicit ".*" at beginning/end (unless you use 
anchors - see the comments in the default lvm.conf) and the '*' will 
match 0 or more occurrences of the preceding character, it actually 
behaves as though there is no '*' there at all.

E.g. "/sdlm*/" would match sdl$ANYTHING, since "m*" is matched by zero 
occurrences of 'm' and the remaining string is consumed by the implicit 
".*" at the end.

Regards,
Bryn.
