Currently in rawhide, the ext4 tracepoint header has some naughty "../../.."
includes, which makes the header unusable from the kernel-devel package. (See
Red Hat bz512478). Since we build the tracepoint query in a single CU, any
failure means that we won't find any tracepoints at all. :(

------- Additional Comments From jistone at redhat dot com 2009-07-21 00:36 -------
My plan is to build a separate tracepoint query module for each header, so
there's no one point of failure. That will take more time to build in pass-2,
but the modules are cached independently of the user's script. Hopefully the
one-time penalty will be acceptable.
The bonus is that this should make it easier to notice when the tracepoint
headers have changed, and we can also throw in support for external tracepoint
headers (e.g. in an out-of-tree kernel module).
