[PATCH] nvme: reject the ns when the block size is smaller than a sector

Re: [PATCH v2] blk: avoid divide-by-zero with zero granularity

Yes, Reject the device is the right fix. I will try to send another fix. By the way, I think this fix is good protection, maybe some other devices violate this block size constraint. Divide zero is unacceptable. Thanks, Feng Li Martin K. Petersen 于2021年1月13日周三 上午1:48写道： > > > Johannes, > > >> I

hwclock make clock_gettime not accurate

HI guys. I'm doing some tests about clock_gettime. And I found that clock_gettime will be affected by hwclock. It makes clock_gettime slip advance some milliseconds. Actually, each line prints out every 1ms. $ ./a.out -r CLOCK_MONOTONIC 130 ↵ Using delay=1 ms between
