Date: Sun, 27 Jan 2013 12:58:36 -0200 From: Fabio Estevam <festevam@...il.com> To: mingo@...nel.org Cc: pjt@...gle.com, linux-kernel@...r.kernel.org, Fabio Estevam <fabio.estevam@...escale.com> Subject: [PATCH] sched: debug: Promote atomic64_read to u64 for printing From: Fabio Estevam <fabio.estevam@...escale.com> commit 2d58000fd (sched: Fix print format for u64) introduced the following build warning for x86_64: kernel/sched/debug.c: In function 'print_cfs_rq': kernel/sched/debug.c:225:2: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 4 has type 'long int' [-Wformat] kernel/sched/debug.c:225:2: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 3 has type 'long int' [-Wformat] atomi64_read() function may have a different returning type depending on the architecture, so in order to guarantee that it builds fine on any system without warnings, promote it to u64 for printing purpose.
