Subject: [PATCH -mmotm/-next] fs: fs_parser: fix printk format warning

From: Randy Dunlap <rdunlap@...radead.org>

Fix printk format warning (seen on i386 builds) by using ptrdiff
format specifier (%t):

../fs/fs_parser.c:413:6: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘int’ [-Wformat=]
