Bart Van Assche 2f1e4e65ba nvmet: avoid integer overflow in the discard code ... [ Upstream commit 8eacd1bd21d6913ec27e6120e9a8733352e191d3 ] Although I'm not sure whether it is a good idea to support large discard commands, I think integer overflow for discard ranges larger than 4 GB should be avoided. This patch avoids that smatch reports the following: drivers/nvme/target/io-cmd-file.c:249:1 nvmet_file_execute_discard() warn: should '((range.nlb)) << req->ns->blksize_shift' be a 64 bit type?
