Subject[PATCH] vfs: make helper function to_mnt_ns static
Date
From: Colin Ian King <colin.king@canonical.com>

The function to_mnt_ns is local to the source and does not need to be
in global scope, so make it static.

Cleans up sparse warning:
symbol 'to_mnt_ns' was not declared. Should it be static?
