Modified Files:
src/sys/dev/raidframe: rf_netbsdkintf.c
Log Message:
Don't merge a good parity map with random stuff in the event that the
first component is missing. (Since the merging just OR's the maps,
this isn't that big of a deal, as it will just over-estimate the
amount of checking that needs to be done.)
