Modified files:
sys/kern vfs_bio.c
Log:
Close a race in biodone(), whereby the bio_done field of the passed
bio may have been freed and reassigned by the wakeup before being
tested after releasing the bdonelock.
There's a non-zero chance this is the cause of a few of the crashes
knocking around with biodone() sitting in the stack backtrace.
