Hi everyone, I've spent some time reworking the watchdog framework, changing it to use sbintime_t instead of power-of-2-nanoseconds. I've thus far tested it only with a software watchdog, but put it up for review to get some feedback on the approach as a whole. The changes are backwards compatible, so drivers don't need to be converted immediately, but can instead be converted over time as needed. The change was brought because at Juniper we have some watchdog timers that don't fit nicely in the power-of-2 nanosecond format, but instead use a simple countdown timer. Moving to sbintime_t (which may even be slightly overkill) gives more freedom with setting the watchdog period. The review is at https://reviews.freebsd.org/D47312 and I would love to get some feedback on it. - Justin
