Alexey V. Khoroshilov (<khoroshilov@xxxxxxxxx>) will soon answer about
the syzbot original, I suppose. Personally, I possess  only Crashlog and
repro.c file which I ran on a local machine and I don't know whether
there is an external report.

As for the solution you proposed, I agree with it: definitely the problem
was caused by an incorrect alignment of max_fds. Frankly speaking, I
didn't know that

because there is no explicit alignment of max_fds value in the code as
I can see.
