We don't plan on enabling this in the generic kernel.
Comment 2 Jens Puhr 2014-03-01 11:50:54 EST
F2FS seems to have an outstanding performance in certain common workloads:


I would also ask to enable the respective kernel module.
Comment 3 Orion Poplawski 2014-12-21 22:07:27 EST
Perhaps it could go into kernel-modules-extra now that we have that?

Okay, you bunch of redhat morons really deserve negative PR as seen on http://www.phoronix.com/scan.php?page=news_item&px=MTg3MDQ 

Its just amazing how some distro and company can be hostile to their users and especially enthusiasts willing to try new technologies here and there. Your bug handling is fucked. And even Ubuntu more sane these days - they supply F2FS by default.
Comment 5 Orion Poplawski 2014-12-22 09:53:53 EST
lnx.usr - Your tone and language are completely inappropriate.

If it is not possible include it in kernel-modules, then yes please.

I plan on opening a new ticket after feedback from the Devel mailing list.  I don't believe requiring uses to install kernel-modules-extra is the way to go on this.  If it's good enough for Ubuntu (which is a distribution aimed at new linux users) it is certainly good enough for Fedora.

Thanks to everyone that has contributed productive information so far.  We'll take a look at this again in a couple of weeks.
Comment 11 Josh Boyer 2014-12-29 15:57:16 EST
I've enabled this in Fedora git.  It will be in the next build of the f20-rawhide kernels.
