Subject: [PATCH] ioctl_ficlonerange.2: mention a subtlety with length == 0
Date: Thu, 14 Jul 2016 11:11:11 -0700	[thread overview]
Message-ID: <20160714181111.GC5215@birch.djwong.org> (raw)

I forgot to document that passing length == 0 to clonerange actually
makes it clone all the way to EOF, so do that now.
