The specific case I'm thinking of had a dependency on some other changes
in -next that weren't targeted for Linus' tree and which triggered only
non-x86 architectures (but fairly obviously on some of them IIRC,
probably something like all*config). With the other changes in -next
everything was fine, and with x86 everything was fine. Most of the
testing on -next is on the integrated tree, though 0day probably should
have triggered.
That interaction with other bits of -next definitely feels like a weak
spot for me when I'm sending changes to Linus.

Or get them into kselftest!
