Subject[PATCH] [V2] NFSv4: add declaration of current_stateid
Date
From: Ben Dooks <ben.dooks@codethink.co.uk>

The current_stateid is exported from nfs4state.c but not
declared in any of the headers. Add to nfs4_fs.h to
remove the following warning:

fs/nfs/nfs4state.c:80:20: warning: symbol 'current_stateid' was not declared. Should it be static?

chnages since v1:
- removed extra definition of current_stateid
- renamed nfs4_stateid_is_current's current_stateid to avoid shadow
