For the plain timers, concurrent use is fine -- it's only a problem for
timer.profile.  This is because of an API change that happened in
2.6.10.  Previously, the profile timer was accessed with
register_profile_notifier, which used a notifier_block (allowing
unlimited registrants).  In 2.6.10 it switched to register_timer_hook,
which uses a single pointer to store the callback (allowing only one
registrant).

Probably someone figured that oprofile was the only one that would ever
use the timer profiler, so this change was an "optimization".  It does
reduce the work for making the callback, but the functionality is more
limited.

Summary of nightly testing 20061016

[William Cohen]

I looked over the test results for this morning for the nightly builds
from oprofile cvs checkout. There are also results for RHEL4 ia64 machine.

The most problematic failure is the timers.stp test causing the rhel4
i686 kernel to crash. This looks to be the same as bz#2726.

The timers.stp probe didn't register on FC5 i686 machine It failed
with rc=-16, "Device or resource busy" because oprofile was already
using the timer. So this means that only one probe could be using the
timer mechanism, and no concurrent use?

The tcptest.stp failed on most of the platforms. When trying to compile
the script by hand it gets a number of errors:
	"failed to retrieve return value location: identifier '$return'"

For
install/share/systemtap/tapset/tcp.stp:159:9
install/share/systemtap/tapset/tcp.stp:129:9

This is looking like there might be a problem with the
debuginformation for some of the kernels.
