[regression] oops on heavy compilations ("kernel BUG at mm/zswap.c:1005!" and "Oops: invalid opcode: 0000")

[Linux regression tracking (Thorsten Leemhuis)]

[to the next one replying: please drop stable@xxxxxxxxxxxxxxx from the
CC, this is just noise there, as this is most likely a mainline regression]

Many thx for the report. And yes, it looks like one. I CCed the zswap
and the mm folks, which a bit of luck they might have an idea. But this
sort of error sometimes is caused by changes in other areas of the
kernel and they just manifest in zswap. If that is the case nobody might
look into this unless you are able to provide more details, like the
result of a bisction
(https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html
) -- that's just how it is...

Ciao, Thorsten
