jimharris 174d031976 nvd: set d_delmaxsize to full capacity of NVMe namespace ... The NVMe specification has no ability to specify a maximum delete size that is less than the full capacity of the namespace - so just using the namespace size is the correct value here. This fixes reported issues where ZFS trim on init looked like it was hanging the system - previously the default I/O max size (128KB on Intel NVMe controllers) was used for delete operations which worked out to only about 8MB/s. With this patch I can add an 800GB DC P3700 drive to a ZFS pool in about 15-20 seconds.
