Ubuntu Wants To Enable SSD TRIM By Default

jones_supa writes "During the first day of the latest virtual Ubuntu Developer Summit, Canonical developers finally plotted out the enabling of TRIM/DISCARD support by default for solid-state drives on Ubuntu 14.04. Ubuntu developers aren't looking to enable discard at the file-system level since it can slow down delete operations, so instead they're wanting to have their own cron job that routinely runs fstrim for TRIMing the system. In the past there has been talk about the TRIM implementation being unoptimized in the kernel. Around when Linux 3.0 was released, OpenSUSE noted that the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance."

WTF? SSDs are important Linus. What is the major malfunction here?

There was a fully functioning implementation on its way into the kernel, but Linus lost it when his only copy of the code was lost because his SSD failed.
