Hmm, I see, they changed some stuff ... and in 2.6.19 too. I made a new 
version that compiles with 2.6.18 and 2.6.19rc4, so try it.

BTW. I've found a weird code in 2.6.19rc4 in vfs_getattr:
generic_fillattr(inode, stat); (ends with stat->blksize = (1 << 
inode->i_blkbits);)
and then
if (!stat->blksize) {...

Someone made this bug when changing it.
