Subject: [PATCH] fs: judging context via current_is_kswapd instead of gfp_flag
Date: Wed, 8 Dec 2021 16:37:38 +0800 [thread overview]
Message-ID: <1638952658-20285-1-git-send-email-huangzhaoyang@gmail.com> (raw)
From: Zhaoyang Huang <zhaoyang.huang@unisoc.com>
Kswapd uses GFP_KERNEL as gfp_flag which make the judgment of
context is unexpected. fix it by using current_is_kswapd.
