This should handle the absolute minimum I need for ZFS. It will register the chdev with the right callbacks. Then the generic registered linux callback will find the right registered solaris callback for the function and munge the args just right before passing it on. Should work, but untested (just compiled), so I expect bugs. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@52 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
