From f95fe9cfb49f6e625fbb5888cae2ed6f3a276b89 Mon Sep 17 00:00:00 2001 From: Herbert Poetzl Date: Tue, 2 Aug 2011 12:43:50 +0200 Subject: block/genhd.c: remove useless cast in diskstats_show() Remove the (unsigned long long) cast in diskstats_show() and adjusts the seq_printf() format string to 'unsigned long' diskstats_show() uses part_stat_read() to get the stats, which either accesses the specified field in the struct disk_stats directly (non SMP) or sums up the per CPU values in a variable of the same type as the field, so in any case the result will have the same type and range as the specified field which for all disk_stats entries is unsigned long Also, for unsigned long ranges the output of %lu should be identical to the one of %llu, so no change in the actual proc entry contents.
