From 157309a97015d8b32d65847d8a6d493d1a958e93 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 6 Dec 2019 08:27:51 +0100 Subject: [PATCH] s390/uv: use EOPNOTSUPP instead of ENOTSUPP ENOTSUP is just an internal kernel error and should never reach userspace. The return value of the share function is not exported to userspace, but to avoid giving bad examples let us use EOPNOTSUPP: Suggested-by: Heiko Carstens Acked-by: Janosch Frank Signed-off-by: Christian Borntraeger Signed-off-by: Vasily Gorbik --- arch/s390/include/asm/uv.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/s390/include/asm/uv.h b/arch/s390/include/asm/uv.h index ef3c00b049ab..4093a2856929 100644 --- a/arch/s390/include/asm/uv.h +++ b/arch/s390/include/asm/uv.h @@ -86,7 +86,7 @@ static inline int share(unsigned long addr, u16 cmd) }; if (!is_prot_virt_guest()) - return -ENOTSUPP; + return -EOPNOTSUPP; /* * Sharing is page wise, if we encounter addresses that are * not page aligned, we assume something went wrong.
