Subject: [PATCH] kprobe: increase kprobe_hash_table size
Date: Fri, 07 Nov 2008 18:44:30 -0500 [thread overview]
Message-ID: <4914D2DE.9030603@redhat.com> (raw)
Increase the size of kprobe hash table to 512. It's useful when hundreds
of kprobes were used in the kernel because current size is just 64.
