It may be handy to use globs or regexps when specifying kprobe function names. Eg (Python):

BPF.attach_kprobe(fn, "vfs_*")

... for globbing, or "vfs_.*" for regexp.

Add regex support to attach_k[ret]probe
5a888c7 
Add new event_re parameter to kprobe functions. This searches through
the list of functions/symbols in <tracefs>/available_filter_functions
for all matching functions. Every one is attached.

Add a test case for attach_k[ret]probe.

Fixes: #141
