Re: lwbuf allocation question?

["Samuel J. Greear" <sjg@xxxxxxxxxxxx>]

What version are you looking at?

http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/sys/cpu/i386/misc/lwbuf.c

Latest doesn't sleep at all, it relies entirely on objcache, which may
sleep internally since objcache_get is being called with M_WAITOK.
