Our current patchset minus the zfstrim one can be found here:- http://blog.multiplay.co.uk/dropzone/freebsd/zfs-trim-patchset83.tbz Of course you'll also need pjd's zfs trim patch set. It expects to be extracted in /usr/src, where it will create a patches subdir. If you then put the zfs trim patch in the same dir and run ./patches/apply.sh you should be good. There's a fare few patches in there, as I've split the various parts into their individual components so its easier to track and submit. The patches include some back ported code that's already committed as well as other little fixes which also have been committed. Notes at the top of each patch file detail what it does and if its been committed. The one to watch is zfs-ashift-fix.patch as that changes how ashift is calculated for a drive (makes it compatible with QUIRKS) but could well cause issues if you booting from a ZFS tank which has a member disk that changes stripsize. If you don't want to risk that, just delete it. It should however be noted that at least on sandforce based disks if your deletes aren't 4k aligned the trim requests will be ignored by the drive, which is what triggered us to create that patch as well as the ssd_quirks.patch Regards Steve ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
