Modified Files: src/sys/dev/sysmon: sysmon_envsys.c sysmon_envsys_events.c sysmonvar.h Log Message: Add a counter of busy events and stop enqueueing more work if a device is busy. Protect this counter with a new short time lock "sme_work_mtx" and keep "sme_mtx" as long time lock. Removes a deadlock where an active event holds "sme_mtx", the callout "sme_events_check" blocks on "sme_mtx" and callout processing stops.
