Some compiler/versions warn these typedefs according to #16660. The platform specific header sys/abd_os.h shouldn't define or use abd_t, as it's defined in its non-platform specific consumer sys/abd.h. Do the same as what FreeBSD header does. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Tomohiro Kusumi <kusumi.tomohiro@gmail.com> Closes #16660 Closes #16665
