mirror_zfs/include/spl-callb.h
behlendo 596e65b4e8 OK, I think this is the last of major cleanup and restructuring.
We've dropped all the linux- prefixes on the file in favor of spl-
which makes more sense.  And we've cleaned up some of the includes
so everybody should be including their own dependencies properly.
All a module which wants to use the spl support needs to do in
include spl.h and ensure it has access to Module.symvers.
