+Subject: [PATCH 07/15] fstatat: fix up behavior on 32/64 bit hosts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The fstatat() syscall is a little funky in that it sometimes changes name
+between 32 and 64 bit hosts, but it should always operate on a 64bit stat
+structure. So for the fstatat() function, make sure we convert it from a
+64bit kstat to a 32bit stat.
+
+Along these lines, we need to restore the __xstat32_conv() function.
