This should be impossible. The error handler API requirement is that the driver relinquish a command once it returns success from any error handling callback ... and if it never returns success, we simply offline the device and never use it again. This is the principle behind the command reuse: we only try an additional command *after* error handling succeeds, so the error handler now owns the command absolutely. > * The lldd succeeds to delete timer and normal completion path runs. > * We're fucked up now.
