>Description:
The MGET section of mbuf(9) asserts that M_DONTWAIT shouldn't be confused with M_NOWAIT ("they are not the same"). In sys/mbuf.h, they are in fact the same, as M_DONTWAIT is merely defined as M_NOWAIT.
Also, M_TRYWAIT is said to wait for kern.ipc.mbuf_wait ticks, a tunable which apparently no longer exists (and really M_TRYWAIT is just M_WAITOK).
