| H A D | kprobes.h | diff e8386a0cb22f4a2d439384212c494ad0bda848fe Tue Jan 06 23:41:52 CET 2009 Masami Hiramatsu <mhiramat@redhat.com> kprobes: support probing module __exit function
Allows kprobes to probe __exit routine. This adds flags member to struct
kprobe. When module is freed(kprobes hooks module_notifier to get this
event), kprobes which probe the functions in that module are set to "Gone"
flag to the flags member. These "Gone" probes are never be enabled.
Users can check the GONE flag through debugfs.
This also removes mod_refcounted, because we couldn't free a module if
kprobe incremented the refcount of that module.
[akpm@linux-foundation.org: document some locking]
