From ef697902a1328e4a205585612c98f476f25b97ef Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Apr 2017 19:39:13 +0200 Subject: [PATCH] lightnvm: assume 64-bit lba numbers The driver uses both u64 and sector_t to refer to offsets, and assigns between the two. This causes one harmless warning when sector_t is 32-bit: drivers/lightnvm/pblk-rb.c: In function 'pblk_rb_write_entry_gc': include/linux/lightnvm.h:215:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow] drivers/lightnvm/pblk-rb.c:324:22: note: in expansion of macro 'ADDR_EMPTY' As the driver is already doing this inconsistently, changing the type won't make it worse and is an easy way to avoid the warning.
