Subject: [PATCH 0/2] Ignore SB_RDONLY when mounting and remounting nfs

When NFS_MOUNT_UNSHARED is not set, NFS forces the sharing of a
superblock among each filesystem that mounts sub-directories elonging to
a single exported root path.

To prevent interference between different filesystems, ignore SB_RDONLY
when mounting and remounting nfs.

Li Lingfeng (2):
  nfs: clear SB_RDONLY before getting superblock
  nfs: ignore SB_RDONLY when remounting nfs
