See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-fsdevel@vger.kernel.org As a rule of thumb everything allocated to the fs_context and moved into the super_block should be freed by ->kill_sb so that the teardown handling doesn't need to be duplicated between the fill_super error path and put_super. Implement an ntfs3-specific kill_sb method to do that.
