From 1e7e2a94ce35a417ce40a2c64c7733cca6782cb9 Mon Sep 17 00:00:00 2001 From: John Spray Date: Fri, 4 Nov 2016 09:34:38 +0000 Subject: [PATCH] doc/cephfs: link in mantle doc ...and add a warning at the very top of the document that it is not for ordinary user use. Considered just not linking this in at all, but it seems a shame to have it here but not be able to e.g. google it and link to it.
