The drivers/gpu/drm/i915/selftests/mock_gem_device.c had a new use of
SLAB_DESTROY_BY_RCU, which obviously conflicted with the rename to
SLAB_TYPESAFE_BY_RCU.
It doesn't show up as a merge-time code conflict, only as a build-time
failure. It's why I do allmodconfig builds after every pull. That
doesn't catch everything (I only do it for x86-64, for example), but
it catches a lot.
And no, it's not a problem. These things happen, and it's literally my
job to make sure my merges work out.
I don't actually expect submaintainers to figure things like that out,
although this *did* show up in linux-next, and it's a bit
disappointing how that information got lost somewhere on the way.
It kind of implies that the prep work that linux-next does doesn't get
fully used.
Normally I wouldn't even have mentioned it, if it wasn't for the fact
that I got a 300kB data dump in my mailbox, and that huge amount of
data wasn't actually even very relevant.
