X-Git-Tag: firefly_0821_release~21870^2~8

[PATCH] restore export of do_kern_mount()

vfs_kern_mount() requires having a reference to fs type, which
makes it impossible for module to create procfs, etc. private
mount.  Open-coding is not an option, since e.g. put_filesystem()
is _not_ exported, and for a good reason.
