Hi all, After merging the akpm tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: ERROR: modpost: ".probe_user_write" [arch/powerpc/kvm/kvm-hv.ko] undefined! Caused by patch "maccess: unexport probe_kernel_write and probe_user_write" "These two functions are not used by any modular code." turns out to not be true :-( I have added this patch: From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Tue, 2 Jun 2020 19:54:05 +1000 Subject: [PATCH] turns out that probe_user_write is used in modular code Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> --- mm/maccess.c | 1 + 1 file changed, 1 insertion(+) diff --git a/mm/maccess.c b/mm/maccess.c index ddfda8e6f4a5..88845eda5047 100644 --- a/mm/maccess.c +++ b/mm/maccess.c @@ -246,6 +246,7 @@ long probe_user_write(void __user *dst, const void *src, size_t size) return -EFAULT; return 0; } +EXPORT_SYMBOL_GPL(probe_user_write); /** * strncpy_from_user_nofault: - Copy a NUL terminated string from unsafe user -- 2.26.2 -- Cheers, Stephen Rothwell
