Description Steven Hartland 2012-10-26 09:50:02 UTC 
Added vfs.zfs.vdev.trim_on_init sysctl which allows full vdev trim on
initialisation to be enabled (1) / disabled (0) defaults to enabled.

This is useful for devices which have a slow trim speed and are either
new or have otherwise already been wiped e.g. secure erase.

Fix: Apply the attached patch
