[PATCH] oprofile: report anonymous region samples
The below patch passes samples from anonymous regions to userspace instead of just dropping them. This provides the support needed for reporting anonymous-region code samples (today: basic accumulated results; later: Java and other dynamically compiled code). As this changes the format, an upgrade to the just-released 0.9 release of the userspace tools is required. This patch is based upon an earlier one by Will Cohen <wcohen@redhat.com> Signed-off-by: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
