Jeff Mahoney ed5c955e31 ecryptfs: don't allow mmap when the lower fs doesn't support it ... commit f0fe970df3838c202ef6c07a4c2b36838ef0a88b upstream. There are legitimate reasons to disallow mmap on certain files, notably in sysfs or procfs. We shouldn't emulate mmap support on file systems that don't offer support natively.
