fs: Warn when filesystem operations are called from a poller
Filesystem operations possibly call into arbitrary devices, so shouldn't
be used from a poller. This patch sprinkles some WARN_ONCE() when this
happens. One exception is when the file which is accessed is on ramfs
which doesn't have any dependencies to devices.
