PROBLEM: zswap+z3fold kernel crashes under memory pressure

From: Nick Bowler
Date: Thu Jun 29 2023 - 21:01:39 EST

Hi,

With 6.4.0, I noticed my system hanging "randomly", eventually
identifying it as being related to memory pressure and ultimately
finding out it is caused by enabling zswap+z3fold. As this seemed
to be a new problem I thought it was a regression but apparently not
-- I can reproduce the exact same problem all the way back with Linux
5.4 (I did not test any earlier versions). So as far as I can tell
this configuration has simply never worked reliably.

There is no similar failure if I use zbud instead of z3fold.

I reproduce the problem with the following program which triggers the
failure 100% of the time in just a matter of seconds:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define CHUNKSZ (1024ul*1024*100)

int main(void)
{
unsigned long long total = 0;
void *p;

while (1) {
p = malloc(CHUNKSZ);
memset(p, 0x5a, CHUNKSZ);

printf("alloced %llu\n", (total += CHUNKSZ));
}
}

When it dies there are a bunch of WARNING messages printed, but only
at higher log levels. With low console log level (1) there is no
indication of any problem except that the system has simply stopped
responding to just about everything (doesn't even respond to ping).
"Just about", because the system does respond to magic sysrq.

Console output at dmesg -n8 follows.

Let me know if you need any more info!

Thanks,
Nick
