Considering that we always disable preemption, it seems useful to switch to raw_smp_processor_id() in several spots, which would exclude the redundant runtime checks compiled into the plain variant. -- Summary: use raw_smp_processor_id more Product: systemtap Version: unspecified Status: NEW Severity: normal Priority: P2 Component: translator AssignedTo: systemtap at sources dot redhat dot com ReportedBy: fche at redhat dot com CC: mhiramat at redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=7049 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 3+ messages in thread
