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.
