Subject: ioctl: implement nvme_set_features_lba_range()
X-Git-Tag: v1.6~13
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=7c483bcd6de0dd4ea218716b47888a9973f8fe1c;p=users%2Fsagi%2Flibnvme.git

ioctl: implement nvme_set_features_lba_range()

nvme_set_features_lba_range() was missing an implementation,
so add one. Change nr_ranges to a u8 since its maximum value is 64.
