[PATCH -tip v2 5/7] kprobes/x86: Fix %p uses in error messages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix %p uses in error messages in kprobes/x86.
- Some %p uses are not needed. Just remove it (or remove message).
- One %p use is right before the BUG() so replaced with %px.
