Not the reiserfs_file_write() ones.

the reiserfs_file_write() code
have an array of b_blocknr_t elements.
It then submits this array to reiserfs_paste_into_item/reiserfs_insert_item,
but b_blocknr_t is unsigned long (read - 64 bit on alpha - oops).
Funny thing is when I declare b_blocknr_t as u32, kernel basically falls apart
if cross compiled. E.g. key comparison does not work and
all kind of weird things start to happen.

In short - if you want to make sure the bug is there - compile 2.5.70+ code
on any 64 bit platform, write any file bigger than 2 blocks,
unmount and remount the fs and see what's in the file.
