  Modified files:
    sys/vm               vnode_pager.c 
  Log:
  Distinguish between two distinct kinds of errors from VOP_BMAP() in
  vnode_pager_generic_getpages(): (1) that VOP_BMAP() is unsupported by the
  underlying file system and (2) an error in performing the VOP_BMAP().
  Previously, vnode_pager_generic_getpages() assumed that all errors were
  of the first type.  If, in fact, the error was of the second type, the
  likely outcome was for the process to become permanently blocked on a busy
  page.
