Re: [PATCH v7 0/5] add compression algorithm zBeWalgo

Hi Benjamin, Today I tried your new patchset but I couldn't go further due to below problem. Unfortunately, I don't have the time to look into. Could you check on it? Thanks. [ 169.597064] zram0: detected capacity change from 1073741824 to 0 [ 177.523268] zram0: detected capacity change from

Re: [PATCH v6 0/5] add compression algorithm zBeWalgo

Hi Benjamin, Thanks for the nice present and good testing! I hope to grab a chance to test this shiny new algorithm but is busy this week. Hopefully, I will get that soon and feedback to you asap. Thanks. On Mon, Mar 26, 2018 at 10:31:40AM +0200, Benjamin Warnke wrote: > This patch series adds
