See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-usb@vger.kernel.org Replace kill_block_super with block_free_sb, which is wired up to the ->free_sb method. For file systems that wrapped kill_block_super, ->kill_sb is replaced with ->shutdown and ->free_sb methods as needed.
