CVS commit: src/sys/ufs/lfs

[Konrad Schroder <perseant%netbsd.org@localhost>]

Module Name:    src
Committed By:   perseant
Date:           Thu Apr 14 00:02:46 UTC 2005

Modified Files:
        src/sys/ufs/lfs: lfs.h lfs_alloc.c lfs_inode.c lfs_segment.c
            lfs_vfsops.c

Log Message:
Keep track of the highest block held by an LFS inode, so that we can
be assured that the last byte of a file is always allocated.  Previously
a file extension could cause the filesystem to be flushed, writing an
inconsistent inode to disk.  Although this condition would be corrected
the next time blocks were written to disk, an intervening crash would leave
the filesystem in an inconsistent state, leaving fsck_lfs to complain
of an inode "partially truncated".
