Jaroslav Kysela fd1bc08d50 ptrace: Convert ptrace_attach() to use lock guards 
JIRA: https://issues.redhat.com/browse/RHEL-27515

commit 5431fdd2c181dd2eac218e45b44deb2925fa48f0
Author: Peter Zijlstra <peterz@infradead.org>
Date: Sun Sep 17 13:24:21 2023 +0200

    ptrace: Convert ptrace_attach() to use lock guards

    Created as testing for the conditional guard infrastructure.
    Specifically this makes use of the following form:

      scoped_cond_guard (mutex_intr, return -ERESTARTNOINTR,
    		     &task->signal->cred_guard_mutex) {
        ...
      }
      ...
      return 0;
