* Let -DINTERRUPTIBLE=0 mask interrupts in probesJosh Stone2009-03-091-0/+11
| | | | | | | | | | | | | | | Some time ago we loosened up the code for all probe types to allow interrupts during the handler. However, when probing something like kernel.trace("*"), you get a mix of probes in and out of the interrupt path, and it becomes much more common to have probes skipped due to interrupt reentrancy. The common_probe_entryfn_prologue and common_probe_entryfn_epilogue functions had an interruptible flag, but this was no longer used anywhere. I removed this flag, but then reused the logic to check an INTERRUPTIBLE macro instead. Now users can use -DINTERRUPTIBLE=0 to prevent interrupt reentrancy in their script, at the cost of a bit more overhead to toggle the interrupt mask.
