However, looking at the other uses of ddi_copy{in,out}() it generally seems that ddi_copy{in,out}() should be defined to copy{in,out}(). With the attached patch at least my simple test cases works again. The one remaining xcopyout() in zfs_ioctl.c then could be also replaced with a ddi_copyout(). Not sure how any of this manages to work on x86 :) Marius _______________________________________________ [hidden email] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-sparc64 To unsubscribe, send any mail to "[hidden email]" |
