Summary: systemd-managed tasks not visible to process probes on
fedora 15
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tapsets
AssignedTo: systemtap@sourceware.org
ReportedBy: fche@redhat.com
CC: dsmith@redhat.com
Due to stap commit #c796d81, stap's task_finder refuses to attach to pid=1.
This is a problem because on fedora 15, systemd hogs pid=1, and forks
service daemons, which renders them invisible to stap probing.
We should remove the pid <= 1 tests from task-finder unless a good reason
for them is found. mjw notes that linux commit 00cd5c37afd5f431ac1 enabled
ptrace on pid=1 some years ago.
