[linux-lvm] lvm filter regex format

I'm trying to be very specific in the global_filter of lvm.conf and
ignore devices under /dev/mapper of the format
'^/dev/mapper/[a-z0-9]{14}$', however the repetition count '{14}' does
not seem to be honored?

Currently I have to repeat '[a-z0-9]' fourteen times, which works but
it's a bit ugly.

Does the filter use some standarized regex format?
