[PATCH] fs/cifs: Fix build warnings

[PATCH] fs/cifs: Fix build warnings

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The sess_alloc_buffer(), sess_free_buffer(), sess_establish_session()
and sess_sendreceive() functions are only used by sess_auth_lanman(),
therefore should be guarded by the same #ifdef to prevent the following
compiler warnings:

	fs/cifs/sess.c:542:1: warning: 'sess_alloc_buffer' defined but not used [-Wunused-function]
	 sess_alloc_buffer(struct sess_data *sess_data, int wct)
	 ^
	fs/cifs/sess.c:580:1: warning: 'sess_free_buffer' defined but not used [-Wunused-function]
	 sess_free_buffer(struct sess_data *sess_data)
	 ^
	fs/cifs/sess.c:589:1: warning: 'sess_establish_session' defined but not used [-Wunused-function]
	 sess_establish_session(struct sess_data *sess_data)
	 ^
	fs/cifs/sess.c:621:1: warning: 'sess_sendreceive' defined but not used [-Wunused-function]
	 sess_sendreceive(struct sess_data *sess_data)
	 ^

I don't see this build warning, and I do see these functions used
outside the CONFIG_CIFS_WEAK_PW_HASH - are you using current
linux-next (or equivalently cifs-2.6.git for-next branch)There were
some updates to fs/cifs late last week.
