Subject: [PATCH 1/2] mm: KSM: fix ksm_run data type
Date: Fri, 16 Jul 2021 00:01:01 +0600	[thread overview]
Message-ID: <343394260f599d940cacc37f1dcc0309239ae220.1626371112.git.zhansayabagdaulet@gmail.com> (raw)
In-Reply-To: <cover.1626371112.git.zhansayabagdaulet@gmail.com>

ksm_run is declared as unsigned long but in run_store(), it is converted
to unsigned int. Change its type to unsigned int.
