- Previously, some startup-time scripts required the "uprobes.ko" module built, installed, or loaded, but the init script did not identify whether and how to do so. A patch has been applied to fix this bug, and the init script now performs the appropriate operations.
- Prior to this update, the systemtap scripts caused the "scheduling while atomic" error when running on the Messaging Real-time Grid kernel. To fix this bug, patches have been applied, and the error no longer occurs.
- The systemtap's "tapset" system call unconditionally included support for the "execveat" system call, even though "execveat" did not exist in Red Hat Enterprise Linux 6 kernels. Consequently, system call probing scripts could fail with a semantic error. With this update, "execveat" is treated conditionally, and the scripts no longer fail in this situation.
