As I read your comment, I can't find the benefit of zram compared to
frontswap.
Well, I am biased, but I agree that frontswap is a better technical
solution than zram. ;-) But "dynamic-ity" is very important to
me and may be less important to others.
I agree that frontswap is better than zram when considering swap as the
use case - no bio overhead, dynamic resizing. However, zram being a
*generic* block-device has some unique cases too like hosting files on
/tmp, various caches under /var or any place where a compressed
in-memory block device can help.
So, frontswap and zram have overlapping use case of swap but are not the
same.
Thanks,
