The filesystem is still there, it is just accessed differently (through /dev nodes) and has been for many years now. We depreciated the filesystem access because it causes lots of confusion for users. The devices file has been full of races and can't be fixed in a sane way, which is why we moved it to debugfs. I am very surprised that your boot process relies on it. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
