CVS commit: src/sys/kern

[Michael van Elst <mlelstv%netbsd.org@localhost>]

Module Name:    src
Committed By:   mlelstv
Date:           Tue Feb 23 20:51:26 UTC 2010

Modified Files:
        src/sys/kern: vfs_wapbl.c

Log Message:
Use correct offset to block number calculations.

Also change access to filesystem blocks to be done by fragment instead
of by physical block. Fragments are the fundamental blocks of the
filesystem.

For a theoretical filesystem that accesses the disk in smaller units
than stored in mp->mnt_fs_bshift, the assumption might be wrong. But
this will also break other subsystems. The value mp->mnt_dev_bshift
which formerly represents the physical sector size is currently only
virtual in NetBSD (always DEV_BSIZE).
