Subject: [PATCH v2 0/2] ptrace: DEBUGCTLMSR_BTF fixes

Hello.

The subject says "ptrace:", but we need these changes for uprobes.

Although I think this fix makes sense by itself. I am really
surprised how many problems this simple code has, or I am
totally confused (this is very possible).

Could someone review 2/2 ?


The next step will change uprobes to use the new helper and avoid
user_enable_single_step().

Oleg.
