[Kernel-packages] [Bug 1063791] Re: ubuntu kernels < 3.7 do not include DISCARD/TRIM (FITRIM ioctl) for JFS filesystem
The fix is in trusty and later, so setting status to fix released. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1063791 Title: ubuntu kernels < 3.7 do not include DISCARD/TRIM (FITRIM ioctl) for JFS filesystem Status in linux package in Ubuntu: Fix Released Bug description: I backported the (now uptream since linux 3.7) patch to add DISCARD/TRIM to JFS filesystem from https://lkml.org/lkml/2012/10/3/250 to ubuntu kernel < 3.7. It contains two other minor fixes, too. It's quite straightforward, the only change is to exclude one line (a call to dquot_writeback_dquots() in fs/jfs/super.c) that otherwise would pull in endless dependencies to newly added blkdev and quota functions and macros. The patched 3.2 kernel (ubuntu generic 3.2.0-31.50, +JFS TRIM + LZO instead of GZIP, no other changes) is up and running on a SSD, 'fstrim' command works and also mount option 'discard'. With the stock ubuntu 3.2 generic kernel on a SSD and JFS, I had two crashes, both inside JFS kernel code, one was catched (AppArmor?) leaving me with r/o filesystem and the other could not recover. Other than that, I experienced bad interactive performance since I installed the SSD. These have become slightly better with the patch added, but interactivity is still worse than with a rotational HD, e.g. when opening a menu. Will now investigate if running a low latency kernel fixes that. The patch is appended, the Ubuntu KernelGitGuide says clone stock linux from kernel.ubuntu.com, but https://wiki.ubuntu.com/Kernel/Dev/KernelPatches says clone stock linux-2.6 from kernel.org, that's all too confusing.

Thanks, guys, for your work. The only release still affected by this bug is precise which will be EOL by the end of this month. It's time to move on.
