Hi,
I was CCed on the "depmod: handle the case of /sbin/depmod without
/sbin in PATH" changes to linux-stable releases.
Do you mind also pushing...?
commit 436e980e2ed526832de822cbf13c317a458b78e1
kbuild: don't hardcode depmod path
That was the origin for the depmod follow-up.
Thanks.

Hi Linus, Hi Mashiro,
thanks for the Linux v5.11-rc1 release.
With a new release I always do my first builds with my distro's
default compiler and linker (GCC v10.2.1 and GNU/ld BFD v2.35.1).
( It's approx. 40% faster than LLVM too

Hi,
When I looked through the code I wondered why we do not add a
"CONFIG_PGO_CLANG_PROFDATA" which can be helpful when doing the PGO
rebuild with a vmlinux.profdata.
This introduces a "PGO_PROFDATA" to turn on/off to pass

Can you add an example for the workload test?
Here I do a x86-64 defconfig build.
See attached script.
Usually, I download this patch from LORE.
