[PATCH] fs/nfs: fix some -Wmissing-prototypes warnings we get a warning when building kernel with W=1: fs/nfs/nfs4file.c:318:1: warning: no previous prototype for ‘nfs42_ssc_open’ [-Wmissing-prototypes] fs/nfs/nfs4file.c:402:6: warning: no previous prototype for ‘nfs42_ssc_close’ [-Wmissing-prototypes]

[Alex]

Add the missing declaration in head file fs/nfs/nfs4_fs.h to fix this.
