Bug Fixes

BZ#1020437
Previously, the kernel added some trace points in a way which failed to expose them to systemtap's search mechanisms. This update extends systemtap's search mechanism to include these extra trace points, thus allowing them to be probed from a systemtap script.
BZ#1027459
The SystemTap runtime could attempt to open a file named "trace1" in the current directory rather than the one that was created in the /sys/kernel/debug/systemtap/ directory. As a consequence, SystemTap terminated unexpectedly if such a file existed in the current directory. This update applies a patch to fix this bug and SystemTap now works as expected in the described scenario.
BZ#1109084
Previously, it was not entirely clear that names of scripts configured with the SystemTap init script service could contain only alphanumeric characters and the underscore character ("_"). Also, the first character in a name cannot be a number. This update adds this information to the systemtap(8) manual page to prevent any confusion.
The systemtap packages have been upgraded to upstream version 2.5-5, which provides a number of bug fixes and enhancements over the previous version. (BZ#1038692, BZ#1074541)
Users of systemtap are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
