Subject: [PATCH 3/5] net: sched: pie: Use ULL suffix for 64-bit constant
Date: Tue, 28 May 2019 16:24:22 +0200	[thread overview]
Message-ID: <20190528142424.19626-4-geert@linux-m68k.org> (raw)
In-Reply-To: <20190528142424.19626-1-geert@linux-m68k.org>

With gcc 4.1, when compiling for a 32-bit platform:

    net/sched/sch_pie.c: In function ‘drop_early’:
    net/sched/sch_pie.c:116: warning: integer constant is too large for ‘long’ type

    net/sched/sch_pie.c:414: warning: integer constant is too large for ‘long’ type

Fix this by adding the missing "ULL" suffix.
