Hi,

This bug will be fixed by the following change.

diff -urN linux-2.4.7-pre6.orig/fs/fat/inode.c linux-2.4.7-pre6/fs/fat/inode.c
--- linux-2.4.7-pre6.orig/fs/fat/inode.c Tue Jun 12 11:15:27 2001
+++ linux-2.4.7-pre6/fs/fat/inode.c Fri Jul 13 04:20:04 2001
@@ -842,7 +842,7 @@
         struct super_block *sb = inode->i_sb;
         struct buffer_head *bh;
         struct msdos_dir_entry *raw_entry;
- int i_pos;
+ unsigned int i_pos;

retry:
         i_pos = MSDOS_I(inode)->i_location;

But, should change ino/i_location/i_pos to unsigned long in
fat/vfat/msdos/umsdos, IMHO.

Thanks.
