      The kernel API posix_acl_valid called by us in mdc_request.c was changed in upstream linux by the following commit:

      commit 0d4d717f25834134bb6f43284f84c8ccee5bbf2a

    vfs: Verify acls are valid within superblock's s_user_ns.
    
    Update posix_acl_valid to verify that an acl is within a user namespace.
    
    Update the callers of posix_acl_valid to pass in an appropriate
    user namespace.  For posix_acl_xattr_set and v9fs_xattr_set_acl pass in
    inode->i_sb->s_user_ns to posix_acl_valid.  For md_unpack_acl pass in
    &init_user_ns as no inode or superblock is in sight.

      Among other things this adds a namespace argument to posix_acl_valid().

      We need to add autoconf support to be able to build with either the old or new version of this kernel API.
