Bug #: 13479
Summary: ARM tapset/scheduler.stp refers to
kernel.function("__switch_to")
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tapsets
AssignedTo: systemtap@sourceware.org
ReportedBy: mjw@redhat.com
Classification: Unclassified
kernel.function("__switch_to") doesn't seem to exist on ARM, but gets selected
in tapset/scheduler.stp because of:
probe __scheduler.ctxswitch.kp =
%( arch != "x86_64" && arch != "ia64" %?
kernel.function("__switch_to")
%:
kernel.function("context_switch")
%)
