    libnvdimm: add support for clear poison list and badblocks for device dax · 006358b3
    Dave Jiang authored Apr 07, 2017
    
    
    Providing mechanism to clear poison list via the ndctl ND_CMD_CLEAR_ERROR
    call. We will update the poison list and also the badblocks at region level
    if the region is in dax mode or in pmem mode and not active. In other
    words we force badblocks to be cleared through write requests if the
    address is currently accessed through a block device, otherwise it can
    only be done via the ioctl+dsm path.
