CVS commit: src/sys/rump/librump/rumpvfs

["Antti Kantee" <pooka%netbsd.org@localhost>]

Module Name:    src
Committed By:   pooka
Date:           Thu Feb  3 15:36:30 UTC 2011

Modified Files:
        src/sys/rump/librump/rumpvfs: rumpblk.c

Log Message:
* open backend device once when the rumpblk is registered instead of
  every time the virtual device is opened.  this takes care of e.g.
  a midlife chmod crisis
* when mapping initial windows, consistently look at host size and
  host offset.  otherwise we might end up in a situation with 0
  initial windows mapped, and that will cause a crash later.
