From: Eric Dumazet Date: Tue, 18 Dec 2007 14:21:13 +0000 (+0100) Subject: sched: sysctl, proc_dointvec_minmax() expects int values for X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73c4efd2c88a41c8a4810904266a34423b5584e5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git sched: sysctl, proc_dointvec_minmax() expects int values for min_sched_granularity_ns, max_sched_granularity_ns, min_wakeup_granularity_ns and max_wakeup_granularity_ns are declared "unsigned long". This is incorrect since proc_dointvec_minmax() expects plain "int" guard values. This bug only triggers on big endian 64 bit arches.
