Recent stability observations with zfs-git under linux-3.17.2

Based on a few reports in the AUR (https://aur.archlinux.org/packages/zfs-git/), some have found instabilities since zfs-git was bumped up to HEAD it seems.  Not wanting to start a discussion in the AUR, I opened this thread.  So what is consensus about the stability of the zfs-git package under the 3.17.2 kernel?  Any problems?  Has anyone succsffully completed a scrub of their zpool under the new packages?

Thanks!

I'm also using the zfs-git package on 4 nodes. I just executed a scrub of the pool of one of the nodes without any issues.

Not seeing any of those lockups or any problems in the journal, also ran a scrub and found zero errors.

Running zfs on root and on another disk, I have no stability problem due to the last upgrade, and no problem during a scrub since the last update.

I had a major slowdown problem, but that was not due to the update but due because the disk was full.

For anyone with a message such as:

It is perfectly fine to upgrade your pool to to the latest disk format as long as you 1) take a good backup before upgrading (you should be doing this regardless), and 2) are fine with not being able to accessing your data using older zpool disk formats. If you are using currently using OpenZFS software (archzfs), your data is already inaccessible with the Oracle zpool disk format. It is still posible to use ZFS send though.

No change in stability for me.
I've successfully run scrubs: firstly before upgrading pool, and also after upgrading pool.

My system has 6 x 4TB in a raidz2; scrubs currently take just under 7hrs.
