6.1-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.
