I just pushed RapidDisk release 2.6 to the git repo. The changelog can be found here: http://rapiddisk.org/index.php?title=Changelog

The changes include a minor rxcache kernel module update: Make spinlocks less greedy by removing most of the "disable ALL interrupts" spinlocks and replacing them with spinlocks to disable interrupts ONLY from bottom halves.

The change was made and tested following a great and recent discussion I had with an employee of a reputable company producing enterprise class Flash SSDs. There should be no noticeable changes with regards to functionality or performance. My post change benchmarks using fio have proven that this is case.

While you can clone/pull the latest source from the official git repository (see rapiddisk.org for details), I also posted a tarball of this release to the Sourceforge project site: https://sourceforge.net/projects/rxdsk/
