Subject: [PATCH v2 0/2] ptrace: DEBUGCTLMSR_BTF fixes
Date: Mon, 13 Aug 2012 15:35:08 +0200 [thread overview]
Message-ID: <20120813133508.GA6703@redhat.com> (raw)
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.
