+From: Brian Behlendorf <behlendorf1@llnl.gov>
+Date: Tue, 26 Apr 2016 17:24:41 -0700
+Subject: [PATCH 8/8] Add support for libtirpc
+
+While OpenSolaris libc and glibc both include XDR support, the musl libc
+does not in favor of depending on the BSD-licensed libtirpc library.
+
+Adding support is a simple matter of detecting the library, including
+the headers and linking against it.  By default libtirpc will be checked
+for and if available used.  Otherwise, configure will fall back to using
+the xdr implementation provided by libc if available.  The options
+--with-tirpc/--without-tirpc can be used to disable this checking.
+
+In addition, the xdr_control() function has been simplied to only
+handle ZFSs specific use case.

+Date: Tue, 26 Apr 2016 17:24:41 -0700
+Subject: [PATCH 8/8] Add support for libtirpc
+
+While OpenSolaris libc and glibc both include XDR support, the musl libc
+does not in favor of depending on the BSD-licensed libtirpc library.
+
+Adding support is a simple matter of detecting the library, including
+the headers and linking against it.  By default libtirpc will be checked
+for and if available used.  Otherwise, configure will fall back to using
+the xdr implementation provided by libc if available.  The options
+--with-tirpc/--without-tirpc can be used to disable this checking.
+
+In addition, the xdr_control() function has been simplied to only
+handle ZFSs specific use case.
