Hi,

What git tree contains this commit? I fetched all of:

git://git.cmpxchg.org/linux-mmots.git master
git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git master
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next-history.git

but I still don't have 05cedaec9b243511f8db62bcd4b1c35c374eba24.

I tried these instructions on the tree which I used to develop the
patch (on top of git://git.cmpxchg.org/linux-mmots.git), but I got:

make[2]: *** No rule to make target 'drivers/spi/spi-bcm53xx.c',
needed by 'drivers/spi/spi-bcm53xx.o'.  Stop.

sorry, that we have regression in code which is solved, but it may mess up some data
and leads to missing info like no exact tree mentioned here. We will continue fixing things up.

For the commit itself, the bot caught it from git://git.cmpxchg.org/linux-mmotm.git, which
is one you mentioned below. Is it possible the commit is rebased?

commit 05cedaec9b243511f8db62bcd4b1c35c374eba24

    arm: port KCOV to arm

    KCOV is code coverage collection facility used, in particular, by
    syzkaller system call fuzzer.  There is some interest in using syzkaller
    on arm devices.  So port KCOV to arm.

Now see it. That's a different tree (mmotm vs mmots).

But I can't reproduce the failure:
