  libceph, rbd, ceph: convert to use the new mount API (2019-11-27 22:28:37 +0100)

----------------------------------------------------------------
The two highlights are a set of improvements to how rbd read-only
mappings are handled and a conversion to the new mount API (slightly
complicated by the fact that we had a common option parsing framework
that called out into rbd and the filesystem instead of them calling
into it).  Also included a few scattered fixes and a MAINTAINERS update
for rbd, adding Dongsheng as a reviewer.

Hmm. Why? That's not a spelling mistake, it's the same word.

Arguably "requeue" isn't much of a real word to begin with, and is
more of a made-up tech language. And then on wiktionary apparently the
only "ing" form you find is the one without the final "e", but
honestly, that's reaching. The word doesn't exist in _real_
dictionaries at all.

I suspect "re-queueing" with the explicit hyphen would be the more
legible spelling (with or without the "e" - both forms are as
correct), but whatever.

I've pulled it, but I really don't think it was misspelled to begin
with, and somebody who actually cares about language probably wouldn't
like either form.

FWIW that was my spelling.  I suspected the same thing, saw it being
used in various spellings, but since Colin is a native speaker I took
the patch.

Thanks,
