Subject[PATCH v3 18/26] NFS: Rename struct nfs_parsed_mount_data to struct nfs_fs_context
Date
From: David Howells <dhowells@redhat.com>

Rename struct nfs_parsed_mount_data to struct nfs_fs_context and rename
pointers to it to "ctx". At some point this will be pointed to by an
fs_context struct's fs_private pointer.
