Subject: [PATCH v2 1/2] mm/damon: simplify the parameter passing for 'check_accesses'
Date: Sat, 27 Aug 2022 17:02:50 +0800 [thread overview]
Message-ID: <1661590971-20893-2-git-send-email-kaixuxia@tencent.com> (raw)
In-Reply-To: <1661590971-20893-1-git-send-email-kaixuxia@tencent.com>
From: Kaixu Xia <kaixuxia@tencent.com>
The parameter 'struct damon_ctx *ctx' isn't used in the functions
__damon_{p,v}a_check_access(), so we can remove it and simplify the
parameter passing.
