Sorry about this.

I have pushed the following fix in the bkl/procfs branch.

Thanks.

    sunrpc: Include missing smp_lock.h
    
    Now that cache_ioctl_procfs() calls the bkl explicitly, we need to
    include the relevant header as well.
    
    This fixes the following build error:
    
    	net/sunrpc/cache.c: In function 'cache_ioctl_procfs':
    	net/sunrpc/cache.c:1355: error: implicit declaration of function 'lock_kernel'
    	net/sunrpc/cache.c:1359: error: implicit declaration of function 'unlock_kernel'
