From ce6cda1845cf2332d2c411a5c72cd166256b21da Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 17 Oct 2013 14:12:56 -0400 Subject: NFS: Add a super_block backpointer to the nfs_server struct NFS_SB() returns the pointer to an nfs_server struct, given a pointer to a super_block. But we have no way to go back the other way. Add a super_block backpointer field so that, given an nfs_server struct, it is easy to get to the filesystem's root dentry.
