Subject: [PATCH 01/24] ubifs: Export ubifs_check_dir_empty()
Date: Thu, 1 Dec 2016 22:20:48 +0100 [thread overview]
Message-ID: <1480627271-10441-2-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1480627271-10441-1-git-send-email-richard@nod.at>
fscrypto will need this function too. Also get struct ubifs_info
from the provided inode. Not all callers will have a reference to
struct ubifs_info.
