      CRED: Fix __task_cred()'s lockdep check and banner comment · 8f92054e
      David Howells 提交于
      Fix __task_cred()'s lockdep check by removing the following validation
      condition:
      
      	lockdep_tasklist_lock_is_held()
      
      as commit_creds() does not take the tasklist_lock, and nor do most of the
      functions that call it, so this check is pointless and it can prevent
      detection of the RCU lock not being held if the tasklist_lock is held.
      
      Instead, add the following validation condition:
      
      	task->exit_state >= 0
      
      to permit the access if the target task is dead and therefore unable to change
      its own credentials.
      
      Fix __task_cred()'s comment to:
      
       (1) discard the bit that says that the caller must prevent the target task
           from being deleted.  That shouldn't need saying.
      
       (2) Add a comment indicating the result of __task_cred() should not be passed
           directly to get_cred(), but rather than get_task_cred() should be used
           instead.
      
      Also put a note into the documentation to enforce this point there too.
