Package: src:linux
Version: 4.19.16-1
Severity: wishlist
Please, enable CONFIG_ZSWAP and its suboptions Z3FOLD and ZBUD.
They are specially important for systems that are very constrained with
memory (in the particular case, a NAS box with 128MB of RAM).
Roger removed them when we were looking to shrink the size of the armel
kernels, but, IIRC, these options were not guilty of bloating the kernel.
I can provide a patch if necessary.
Thanks,
Rogério Brito.
