Hi,
Here are the patches for fixing bugs in kprobes on x86.
- Both bugs are related to the optprobe. - First bugfix is optprobe to recover instructions when thoes are modified with jump. - Second bugfix is kprobes to recover it too.
This series also includes a patch which split optprobes parts out from kprobes x86 implementation.
Ingo, I've added the splitting patch according your advice :)
Thank you,
