Greg Kroah-Hartman 91be4236fb ANDROID: GKI: remove vfs-only namespace from 2 symbols ...

Commit d483eed85f ("ANDROID: GKI: set vfs-only exports into their own
namespace") moved a bunch of symbols into a vfs-only namespace to make
it possible for some external filesystem modules to be able to use them.
Unfortunately the following two symbols were already being marked used by
external modules, and moving them into a different namespace broke
existing users of these symbols:
	kern_path
	__sync_dirty_buffer

The ABI checking tools do not take the namespace of the symbol into
consideration when checking, as that is a Linux kernel "add-on" and not
part of the kernel symbol table information directly, which is why this
was not caught earlier.
