Hi,

Here is a series of patches which improves perf-probe to add
filtering features for --list,--del and --funcs. This also
includes some bugfixes and cleanups.

E.g. --list/--funcs accepts filter rules.
----
# ./perf probe -l vfs\*
probe:vfs_read (on vfs_read@ksrc/linux-3/fs/read_write.c)
# ./perf probe -l \*libc:\*
probe_libc:malloc (on __libc_malloc@malloc/malloc.c in /usr/lib64/libc-2.17.so)
----
----
# ./perf probe -F *kmalloc
__kmalloc
devm_kmalloc
mempool_kmalloc
sg_kmalloc
sock_kmalloc
----

Also, --del accepts filter rules too which is more flexible than
simple wildcard.
----
# ./perf probe -d 'vfs*|malloc'
Removed event: probe:vfs_read
Removed event: probe_libc:malloc
----

Thank you,

---
