Subject: [PATCH AUTOSEL 4.14 09/13] arch/arc: add copy_user_page() to <asm/page.h> to fix build error on ARC
Date: Tue, 12 Jan 2021 07:57:45 -0500 [thread overview]
Message-ID: <20210112125749.71193-9-sashal@kernel.org> (raw)
In-Reply-To: <20210112125749.71193-1-sashal@kernel.org>
From: Randy Dunlap <rdunlap@infradead.org>
[ Upstream commit 8a48c0a3360bf2bf4f40c980d0ec216e770e58ee ]
fs/dax.c uses copy_user_page() but ARC does not provide that interface,
resulting in a build error.
Provide copy_user_page() in <asm/page.h>.
../fs/dax.c: In function 'copy_cow_page_dax':
../fs/dax.c:702:2: error: implicit declaration of function 'copy_user_page'; did you mean 'copy_to_user_page'? [-Werror=implicit-function-declaration]
