Modified files:
sys/sys buf.h
Log:
The BUF_*() routines must be internally splbio() protected otherwise they
can cause a biodone() from a disk interrupt to spin when the interrupt
code tries to grab the simplelock. Masking BIO here means buftimelock
and/or lk->lk_interlock shouldn't be held when an interrupt tries to grab
them.
