Hi, I have two issues with zswap. I am running 3.11.0-13-generic #20~precise2-Ubuntu. The zswap doc says that I can run a custom compessor and suggests, as an example in the doc to use, for example, zswap.compressor=deflate as a kernel option. But when I do that dmesg says "zswap: deflate compressor not available" and send me back to the default lzo compressor. Trying lz4 gets the same note. Is this a bug or a feature, and where should this be reported to? I wonder why the default compressor is lzo. I understand that, roughly, lz4 would achieve roughly the same compression and takes roughly the same effort to compress, but decompresses much faster. If my understanding is correct, a compressed page is likely to be decompressed several times while it stays in the pool. I therefore suspect that lz4 it would be a better compressor for zswap than lzo. Am I way off base here? -- Cheers, Thomas Krichel http://openlib.org/home/krichel skype:thomaskrichel _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
