Hi Jens, Please take a look at these three patches for 4.4-rc2.
The first patch uses a slab allocator for ppa list to only allocate the necessary memory. As the linear addressing mode was removed, the second patch changes the driver to use the ppa format adressing mode and at last, the third patch fixes two bugs. One when freeing gendisk on unload and another to pass a null pointer to lightnvm unregister function. Feel free to fold them into the original null_blk patch. Matias Bjørling (3): null_blk: use ppa_cache pool null_blk: use device addressing mode null_blk: do not del gendisk with lightnvm drivers/block/null_blk.c | 62 ++++++++++++++++++++++++++++++++++++++++-------- 1 file changed, 52 insertions(+), 10 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
