[PATCH 001/001] hostfs: set maximum filesize in superblock for proper LFS support

[Wolfgang Illmeyer]

From: Wolfgang Illmeyer <wolfgang@xxxxxxxxxxxx>

Maximum file size for hostfs mounts defaults to 2GB, so bigger files cannot be 
read/written through hostfs. This patch initializes the maximum file size to 
MAX_LFS_SIZE.

This patch applies against linux-2.6.30. It fixes 
http://bugzilla.kernel.org/show_bug.cgi?id=13531
It is a revamped version of the patch I attached to the bug, using additional 
input from Andrew Morton (thanks). This is my first patch for the kernel, I 
hope I didn't break too many rules ;)

For any feedback from the mailing list please add me to "To" or CC me - I'm 
not on the list.
