KOSAKI Motohiro bd6daba909 procfs: make errno values consistent when open pident vs exit(2) race occurs ... proc_pident_instantiate() has following call flow. proc_pident_lookup() proc_pident_instantiate() proc_pid_make_inode() And, proc_pident_lookup() has following error handling. const struct pid_entry *p, *last; error = ERR_PTR(-ENOENT); if (!task) goto out_no_task; Then, proc_pident_instantiate should return ENOENT too when racing against exit(2) occur. EINAL has two bad reason. - it implies caller is wrong. bad the race isn't caller's mistake. - man 2 open don't explain EINVAL. user often don't handle it. Note: Other proc_pid_make_inode() caller already use ENOENT properly. Acked-by: Eric W.
