Subject: linux-next: build failure while building Linus' tree
Date: Thu, 9 Sep 2021 18:25:25 +1000 [thread overview]
Message-ID: <20210909182525.372ee687@canb.auug.org.au> (raw)

Hi all,
Building Linus' tree, today's linux-next build (powerpc
ppc6xx_defconfig gcc4.9) failed like this:
ERROR: modpost: "__divdi3" [drivers/block/nbd.ko] undefined!
Caused by commit
fad7cd3310db ("nbd: add the check to prevent overflow in __nbd_ioctl()")
The added check_mul_overflow() call is being passed 64 bit values.
COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW is not set for this build (see
include/linux/overflow.h).

Cheers,
Stephen Rothwell
