arc: hsdk_defconfig: Enable CONFIG_BLK_DEV_RAM Browse files We have now a HSDK device in our kernelci lab, but kernel builded via the hsdk_defconfig lacks ramfs supports, so it cannot boot kernelci jobs yet. So this patch enable CONFIG_BLK_DEV_RAM in hsdk_defconfig. Signed-off-by...

Thenull-blockdevice (/dev/nullb*) emulates a block device with a size of X GB. Its purpose is to test the different block-layer implementations. Instead of performing read/write operations, it simply registers them as finished in the request queue. Create a null-block device /dev/nullb0:...
