Hi Chris, Does zswap actually keep the data compressed when the DRAM-based swap is full, and it writes to the spill-over non-volatile swap device?
I'm not an expert on this at all, however my understanding was that zswap must decompress the data before it writes to the backing swap. But perhaps I am misunderstanding the purpose of zswap_writeback_entry()[1] and/or what it does.
