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 > sane_fdtable_size() really should never return a value that > isn't BITS_PER_LONG aligned because there is no explicit alignment of max_fds value in the code as I can see.
