Hi folks, I receive bug reports from partners for the bcache cache device failure handling patch set (which is just merged into 4.17). Fortunately we are still in 4.17 merge window, so I ask helps for offering code review before I ask Jens to pick these fixes for 4.17-rc3.
The patches are well commneted IMHO and passes regression test by myself. Thanks for your help in advance.
