Subject: [PATCH trivial] include/linux/huge_mm.h: Return NULL instead of false for pmd_trans_huge_lock()
Date: Mon, 28 Mar 2016 22:49:54 +0800 [thread overview]
Message-ID: <1459176594-1881-1-git-send-email-chengang@emindsoft.com.cn> (raw)
From: Chen Gang <chengang@emindsoft.com.cn>
The return value of pmd_trans_huge_lock() is a pointer, not a boolean
value, so use NULL instead of false as the return value.
