Subject: [PATCH v2 sched_ext/for-7.3 06/36] tools/sched_ext: scx_qmap - Use bare u64/u32/s32 integer types
Date: Sun,  5 Jul 2026 15:40:28 -1000	[thread overview]
Message-ID: <20260706014058.439853-7-tj@kernel.org> (raw)
In-Reply-To: <20260706014058.439853-1-tj@kernel.org>

scx_qmap.c and the shared scx_qmap.h mixed __u64/__u32/__s32 with the bare
typedefs that scx/common.h provides. Convert the remaining __-prefixed
integer types to the bare forms for consistency. The struct fields become
bare u64 (uint64_t), so the stats printfs that fed them to %llu now cast to
unsigned long long. No functional change.

Signed-off-by: Tejun Heo <tj@kernel.org>
