  Module Name:    src
  Committed By:   chs
  Date:           Fri May 20 13:16:54 UTC 2005

  Modified Files:
          src/sys/miscfs/kernfs: kernfs.h kernfs_vnops.c

  Log Message:
  kernfs does not support mmap(), remove code that pretends that it does.


  To generate a diff of this commit:  
  cvs rdiff -r1.23 -r1.24 src/sys/miscfs/kernfs/kernfs.h
  cvs rdiff -r1.107 -r1.108 src/sys/miscfs/kernfs/kernfs_vnops.c


so now mmap() will fail for kernfs files (like it used to before about
a year ago), and program should fall back to read(), which works fine.
