I'd need to figure out exactly what the restrictions are and like I say the name of the function itself is confusing, I suspect because it predates SMP.

Actually yes, though not immediately. Another option is to just rename the current function and all the callers en masse then add a new, safe mod_delayed_work(). [unhandled content-type:application/pgp-signature] | |
