+Subject: [PATCH] Use AC_HEADER_MAJOR to detect major()/minor()/makedev()
+
+commit af6824fce9c9536fbcabef8d5547f6c486f55fdf from
+git://github.com/lxc/lxc.git
+
+Before the change build failed on Gentoo as:
+
+  bdev/lxclvm.c: In function 'lvm_detect':
+  bdev/lxclvm.c:140:4: error: implicit declaration of function 'major' [-Werror=implicit-function-declaration]
+    major(statbuf.st_rdev), minor(statbuf.st_rdev));
+    ^~~~~
+  bdev/lxclvm.c:140:28: error: implicit declaration of function 'minor' [-Werror=implicit-function-declaration]
+    major(statbuf.st_rdev), minor(statbuf.st_rdev));
+                            ^~~~~
+
+glibc plans to remove <sys/sysmacros.h> from glibc's <sys/types.h>:
+    https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html
+
+Gentoo already applied glibc patch to experimental glibc-2.24
+to start preparingfor the change.
+
+Autoconf has AC_HEADER_MAJOR to find out which header defines
+reqiured macros:
+    https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Particular-Headers.html
+
+This change should also increase portability across other libcs.
