As just said your patch is wrong for vanilla 2.2.18pre23.

The right fix for that problem in 2.2.18pre23 (2.2.x vanilla doesn't include
LFS) is here:

ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.18pre22/lseek-2g-ext2-1

I also uploaded separately your right fix for /dev/mem:

ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.18pre22/lseek-2g-mem-hjl-1 (this one is

and this the right fix for the largefile handling in ext2:

ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.18pre22/notify-change-2g-ext2-1

All three should be applied to 2.2.18pre-latest.

And in LFS (that means also 2.4.x) the >> 32 doesn't make any sense in lseek
and should be removed:

ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/patches/v2.4/2.4.0-test11-pre6/ext2-lseek-cleanup-1
