Subject: [PATCH v4 0/1] vfs: Respect MS_RDONLY at bind mount creation

Dear Linus,

Here is the patch that we discussed at LinuxCon Europe. My plan was to send it
the week after LinuxCon Europe (last week) as you had asked. However, I caught
somethng at the conference and was sick last week, so that was delayed.

The history of the patch is that the v1 was done in July. I sent v2 shortly
afterward upon realizing that v1 did not take the opportunity atomically close
the race with respect to bind mounting and marking readonly. v3 and v4 followed
with feedback from Mateusz Guzik, but aside from him, no one else replied.

Then at LinuxCon Europe, I spoke briefly to Mauro Carvalho Chehab, Ted T'so and
yourself about it. Mauro thought it looked okay, but he told me not to include
his ACKed by because he is not involved in this subsystem. Ted was surprised
that this was even a bug. The two of us spoke about so many filesystem things
that I neglected to ask if including him as ACKed by was okay. I have CCed
Mateusz, Ted, Mauro, the usual people from get_maintainers.pl and other
interested parties.

Yours truly,
Richard Yao
