2.6.27+ portability changes - Added SPL_AC_3ARGS_ON_EACH_CPU configure check to determine if the older 4 argument version of on_each_cpu() should be used or the new 3 argument version. The retry argument was dropped in the new API which was never used anyway. - Updated work queue compatibility wrappers. The old way this worked was to pass a data point when initialized the workqueue. The new API assumed the work item is embedding in a structure and we us container_of() to find that data pointer. - Updated skc->skc_flags to be an unsigned long which is now type checked in the bit operations. This silences the warnings. - Updated autogen products and splat tests accordingly 2009-02-03 02:12:30 +03:00			`#ifndef _SPL_SMP_COMPAT_H`
