Date: Fri, 25 Nov 2022 12:12:49 +0200 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: linux-kbuild@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Masahiro Yamada <masahiroy@...nel.org>, Nathan Chancellor <nathan@...nel.org>, Nick Desaulniers <ndesaulniers@...gle.com>, Nicolas Schier <nicolas@...sle.eu>, Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH v1 1/1] modpost: Mark uuid_le type to be suitable only for MEI The uuid_le type is used only in MEI ABI, do not advertise it for others. While at it, comment out that UUID types are not to be used in a new code. Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> --- If you confused by acrn user of the uuid_le type, the patch to fix that is pending for v6.2 as well 1dbb4f0235a4 ("virt: acrn: Mark the uuid field as unused"). Nevertheless this patch doesn't break the things and hence can go independently to the respective tree. scripts/mod/file2alias.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) diff --git a/scripts/mod/file2alias.c b/scripts/mod/file2alias.c index 7df23905fdf1..91c2e7ba5e52 100644 --- a/scripts/mod/file2alias.c +++ b/scripts/mod/file2alias.c @@ -34,19 +34,23 @@ typedef Elf64_Addr kernel_ulong_t; typedef uint32_t __u32; typedef uint16_t __u16; typedef unsigned char __u8; + +/* UUID types for backward compatibility, don't use in new code */ typedef struct { __u8 b[16]; } guid_t; -/* backwards compatibility, don't use in new code */ -typedef struct { - __u8 b[16]; -} uuid_le; typedef struct { __u8 b[16]; } uuid_t; + #define UUID_STRING_LEN 36 +/* MEI UUID type, don't use anywhere else */ +typedef struct { + __u8 b[16]; +} uuid_le; + /* Big exception to the "don't include kernel headers into userspace, which * even potentially has different endianness and word sizes, since * we handle those differences explicitly below */ -- 2.35.1
