We'd return -1 (-EPERM), even though we have a general rule to use real errno values. The particular case that caught my attention was: $ sudo udevadm control -l asdf Failed to parse log priority 'asdf': Operation not permitted ... but "git grep 'r =.*_from_string' src/" return 110 hits. Confusingly, some of the _from_string functions already return a proper errno value, so not all of those are broken, but probably quite a few.
