Subject[PATCH v4 -tip 0/3] x86/kprobes: bugfixes and split optprobes
Date
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,
