6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Hindborg <a.hindborg@xxxxxxxxxxx>
[ Upstream commit b8673d56935c32a4e0a1a0b40951fdd313dbf340 ]
Symbols in the bss segment are not currently exported. This is a problem
for Rust modules that link against statics, that are resident in the kernel
image. Thus export symbols in the bss segment.
Fixes: 2f7ab1267dc9 ("Kbuild: add Rust support")
