[Devel] [PATCH hci-8.1] selftests/zram: use the device ids that hot_add returns

[no-reply at sashiko.virtuozzo.com]

> zram_load() numbers the devices it creates by counting the nodes in
> /dev and discards the ids hot_add returns. hot_add takes the lowest
> free id, so once the ids have a gap the test works on a device it did
> not create: with zram0 and zram2 present it creates zram1, then
> configures, formats and mounts zram2, and finally resets and removes
> zram2 and leaves zram1 behind.
> 
> Keep the ids hot_add returns and use them in every step and in the
> cleanup. A hot_add that fails now fails the test.
> 
> Fixes: 01dabed20573 ("selftests/zram: Adapt the situation that /dev/zram0 is being used")
> https://virtuozzo.atlassian.net/browse/VSTOR-152656
> Feature: fix selftests
