From a623d31805eab7da9eda300e275bd8bf7e92a98c Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Thu, 5 Jan 2023 12:51:45 -0800 Subject: [PATCH] block: make BLK_DEF_MAX_SECTORS unsigned [ Upstream commit 0a26f327e46c203229e72c823dfec71a2b405ec5 ] This is used as an unsigned value, so define it that way to avoid having to cast it.
