This commit was pipped to the post by a similar patch [0] from Felipe Balbi

https://lore.kernel.org/lkml/20190215112938.25574-1-felipe.balbi@linux.intel.com/

Combined together they would form a complete patch, but this one could
do with the Fixes: tag such as

Fixes: e262e32d6bde "vfs: Suppress MS_* flag defs within the kernel
unless explicitly enabled"

With a Fixes: tag:

Whereas Felipe's patch does not include this change (which I think it
looks like it should)


How should we proceed with these two competing patches?
Any preference from anyone?

Content wise, I feel like this one is in the lead - just missing the
Fixes: tag, but Felipe's won the race...
