I'd like to lodge a bitter complaint about the return codes used by queue_work() and related functions:

Why do the damn things return 0 for error and 1 for success???
Why don't they use negative error codes for failure, like everything else in the kernel?!!

It's a standard programming idiom: return false (0) for failure, true (non-zero) for success. Boolean.

Certainly the kernel often uses the -errno convention, but it's not a rule.
