With the update to onnv_141 the zero-copy API we've been waiting for has been added. This means we can stop faking it in zpios. The zpios code must be updated to use the new API, for now this support is simply disabled.

Closing issue, it's unlikely we'll ever need/want this now that we fall a full ZPL in place.

Prevent deadlock in arc_read in Linux memory reclaim callback
6ac3449 
Using zfs with Lustre, an arc_read can trigger kernel memory allocation
that in turn leads to a memory reclaim callback and a deadlock within a
single zfs process. This change uses spl_fstrans_mark and
spl_trans_unmark to prevent the reclaim attempt and the deadlock
(https://zfsonlinux.topicbox.com/groups/zfs-devel/T4db2c705ec1804ba).
