From: Fabio Estevam <fabio.este...@freescale.com>

The following build warning is seen when building for ARM:

fs/btrfs/disk-io.c:3927:21: warning: format '%lu' expects argument of type 
'long unsigned int', but argument 3 has type 'unsigned int' [-Wformat]

Use the '%zu' specifier when printing 'sizeof'.
