Asked some of the folks to pipe in, but in the mean-time here are some links. >From Oracle: Kurt Hackel says "interest in seeing frontswap merged upstream" because it is already used in OracleVM. https://lkml.org/lkml/2011/10/27/215 Avi Miller says "we see this as a critical feature." https://lkml.org/lkml/2011/10/27/252 (product manager). Some Android ports have picked it up [mainly to use zcache which depends on frontswap]: - An LG and HTC kernel ROM has incorporated frontswap. http://androidforums.com/spectrum-all-things-root/522953-rom-5-26-12-broken-out-spectrum-3-0-w-blitzkrieg-kernel.html - A GalaxyS-based kernel port has included frontswap. http://hdtechvideo.com/community/index.php?threads/devil2_0-94.245/ - CyanogenMod just added frontswap. http://www.andro9.in/2012/05/cyanogenmod-9-ics-404-weeklies-for-lg.html Many people piped up last year at a previous merge proposal. Here are some from LKML postings: - Brian King says IBM is actively looking at utilizing frontswap for IBM Power and would welcome its inclusion in mainline. https://lkml.org/lkml/2011/10/27/273 - Nitin Gupta, author of zram, has stated that zcache is in many ways superior to zram... but this assumes frontswap is merged. https://lkml.org/lkml/2011/10/28/8 - Ed Tomlinson says "I'd love to see this in the kernel." https://lkml.org/lkml/2011/10/29/53 - Sasha Levin and "CJ" worked on the KVM PoC and commented that https://lkml.org/lkml/2011/10/28/8 - Ed Tomlinson says "I'd love to see this in the kernel." https://lkml.org/lkml/2011/10/29/53 - While Andrea Arcangeli voiced objections last year https://lkml.org/lkml/2011/10/31/186 he expressed at LSF/MM 2012 that many of his issues are now resolved and sufficient progress has been made to merge frontswap (with more work needed in zcache before zcache can be promoted out of staging). - James Bottomley requested more benchmarking on zcache and some excellent results were published and presented at LSF/MM 2012. http://lwn.net/Articles/490501/ - Valdis Kletnieks points out that he needs it in machines that are maxed out on RAM. https://lkml.org/lkml/2011/11/6/157 Thanks! -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
