Subject: [Bug runtime/5194] New: IO problem on begin/end probes
Date: Thu, 18 Oct 2007 14:01:00 -0000 [thread overview]
Message-ID: <20071018140048.5194.hunt@redhat.com> (raw)
begin and end probes are now interruptible. This creates a problem with IO
because we use percpu buffers.
A possible solution would be to have the translator add a call to
smp_processor_id() to the probe prologue and modify the print functions to take
a cpu input instead of each calling smp_processor)id().
