HARDWARE --
The libata updates for the Linux 4.2 kernel may be of interest this time around for solid-state drive owners thanks to some NCQ TRIM improvements.

Tejun Heo noted in the pull request, "a number of libata core changes to better support NCQ TRIM."

With this pull request also comes new kernel parameters for enabling/disabling NCQ TRIM. The new kernel parameters are ncqtrim and noncqtrim. These options were added since newer SSD firmwares are adding support for queued trim, but in many cases the firmware TRIM support is untested and has been leading to errors or data corruption for users.

The libata changes in full for Linux 4.2 can be read about via this mailing list post.
