Subject: [PATCH v2] VFS: Handle lazytime in do_mount()
Date: Tue, 19 Sep 2017 12:37:24 +0200	[thread overview]
Message-ID: <20170919103724.GA239@x4> (raw)
In-Reply-To: <20170919101819.GA233@x4>

Since commit e462ec50cb5fa ("VFS: Differentiate mount flags (MS_*) from
internal superblock flags") the lazytime mount option didn't get passed
on anymore.

Fix the issue by handling the option in do_mount().
