If you look into vdso_config.h in selftests, you can see that > there are two names: > > __kernel_getrandom is used on arm64, powerpc, s390, > > __vdso_getrandom is used on arm, mips, sparc, x86, riscv, loongarch I thought about this too, but actually it looks like the __vdso_* ones are already being handled this way, while the __kernel_* ones have their own special thing going on. See include/vdso/gettime.h. So this patch makes __vdso_getrandom() just like the other ones in gettime.h, which is fine with me.
