CVS commit: src/sys/dev

["Izumi Tsutsui" <tsutsui%netbsd.org@localhost>]

Module Name:    src
Committed By:   tsutsui
Date:           Sat Jun 30 10:52:32 UTC 2012

Modified Files:
        src/sys/dev: md.c

Log Message:
Make sure that disklabel of md(4) device is initialized
in the case where it's configured in MD md_open_hook().

Without this, msdosfs_mountfs() (which is called from msdosfs_mountroot())
will be called with uninitialized disklabel (d_secsize == 0) and
it gets "panic: buf mem pool index 23" later on atari.
This is because getdisksize() doesn't check returned d_secsize value
and msdosfs_mountfs() blindly calls bread(9) with size==0 in that case.

Should be pulled up to netbsd-6 (at least for atari).
