Subject: [PATCH V5 6/9] f2fs: use IS_VERITY() to check inode's fsverity status
Date: Wed, 12 Dec 2018 15:20:15 +0530	[thread overview]
Message-ID: <20181212095018.12648-7-chandan@linux.vnet.ibm.com> (raw)
In-Reply-To: <20181212095018.12648-1-chandan@linux.vnet.ibm.com>

This commit removes the f2fs specific f2fs_verity_file() and makes use
of the generic IS_VERITY() macro or file_is_verity() to check for the
verity status of an inode.
