Patch for master branch to make posix.sh support BASELINE_FS=zfs is in http://review.whamcloud.com/8180.
After the patch is ready to land, it can also be cherry-picked to Lustre b2_4 branch.

After applying the above patch on Lustre b2_4 build #49, I manually ran posix test with FSTYPE=zfs and got the following test results:

All of the "Unresolved" failures are LU-3603. I'll investigate the "Failed" failures.

[Andreas Dilger]

I think all of the pathconf failures may be caused by pathconf being hard coded in glibc based on the Filesystem magic number. That means it isn't possible to change the value for Lustre without recompiling glibc.

Not sure if the other failures. It would be useful to file subtickets for the failures with the text from the failing tests.

Besides LU-3603, LU-4219 and LU-4220 were created to track the failures.
