NFS: Additional refactoring for fs_context conversion
Split out from commit "NFS: Add fs_context support." This patch adds additional refactoring for the conversion of NFS to use fs_context, namely: (*) Merge nfs_mount_info and nfs_clone_mount into nfs_fs_context. nfs_clone_mount has had several fields removed, and nfs_mount_info has been removed altogether. (*) Various functions now take an fs_context as an argument instead of nfs_mount_info, nfs_fs_context, etc. Signed-off-by: Scott Mayhew <smayhew@redhat.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
