Linux patch for reading ufs2

[Vladimir Kushnir]

Hi,
This is /usr/ports/distfiles/emovix-0.8.0.tar.gz - regular file, "ls -li":
1842130 -rw-r--r--  1 vkushnir  wheel  8636010 Jan  5 
23:43 /usr/ports/distfiles/emovix-0.8.0.tar.gz

I don't know precisely what's relevant but after (lengthy indeed) debugging 
information Linux gives:
......
Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 543), ufs_read_inode: 
ENTER, ino 1842130
Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 636), ufs_read_inode: 
Reading ufs2 inode, ino 184213
Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 704), ufs_read_inode: EXIT
Feb 15 18:34:06 localhost kernel: attempt to access beyond end of device

block 536870972
and so on - several blocks in this region (here hd10 == ad0s2e, /usr, mounted 
under Linux with "-r -t ufs -o ufstype=ufs2"). And finally it refuses to copy 
or untar this file. This is the only information I cn see there. 
At the same time when I boot into FreeBSD - no problems whatsoever.
