I gave the latest master a run using ZFS with a linux 4.5.7 kernel and found new regression. One of the changes for the 4.5 kernel is the removal of GFP_IOFS. In the past I submitted a patch to remove this flag in the server code but I was told it was needed. Now in newer kernels the lack of GFP_IOFS needs to be addressed.
