[Bug runtime/13146] New: memory allocation can sleep


http://sourceware.org/bugzilla/show_bug.cgi?id=13146

             Bug #: 13146
           Summary: memory allocation can sleep
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sourceware.org
        ReportedBy: dsmith@redhat.com
    Classification: Unclassified


When the systemtap runtime allocates memory, it uses GFP_KERNEL (possibly with
other flags).  GFP_KERNEL includes __GFP_WAIT, which means that the memory
allocation could possibly sleep.

Systemtap probe handlers should not sleep.
