As it turns out, on the Windows platform when rw_init() is called (rather its bedrock call ExInitializeResourceLite) it is placed on an active-list of locks, and is removed at rw_destroy() time. dnode_move() has logic to copy over the old-dnode to new-dnode, including calling dmu_zfetch_init(new-dnode). But due to the missing dmu_zfetch_fini(old-dnode), kmem will call dnode_dest() to release the memory (and in debug builds fill pattern 0xdeadbeef) over the Windows active-lock's prev/next list pointers, making Windows sad. But on other platforms, the contents of dmu_zfetch_fini() is one call to list_destroy() and one to rw_destroy(), which is effectively a no-op call and is not required. This commit is mostly for "correctness" and can be skipped there. Porting Notes: * This leak exists on Linux but currently can never happen because the dnode_move() functionality is not supported. openzfsonosx-commit: openzfsonosx/zfs@d95fe517 Authored by: Julian Heuking <JulianH@beckhoff.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Matt Ahrens <mahrens@delphix.com> Signed-off-by: Jorgen Lundman <lundman@lundman.net> Closes #8519
