Subject[PATCH] cifs: hide unused functions
Date
The newly added SMB2+ attribute support causes unused function
warnings when CONFIG_CIFS_XATTR is disabled:

fs/cifs/smb2ops.c:563:1: error: 'smb2_set_ea' defined but not used [-Werror=unused-function]
smb2_set_ea(const unsigned int xid, struct cifs_tcon *tcon,
fs/cifs/smb2ops.c:513:1: error: 'smb2_query_eas' defined but not used [-Werror=unused-function]
smb2_query_eas(const unsigned int xid, struct cifs_tcon *tcon,

This adds another #ifdef around the affected functions.

Fixes: 5517554e4313 ("cifs: Add support for writing attributes on SMB2+")
Fixes: 95907fea4fd8 ("cifs: Add support for reading attributes on SMB2+")
