[Cluster-devel] [PATCH 31/48] [GFS2] be*_add_cpu conversion



From: Marcin Slusarz <marcin slusarz gmail com>

replace all:
big_endian_variable = cpu_to_beX(beX_to_cpu(big_endian_variable) +
					expression_in_cpu_byteorder);
with:
	beX_add_cpu(&big_endian_variable, expression_in_cpu_byteorder);
generated with semantic patch
