+Subject: [PATCH] Add dummy definition of O_CLOEXEC
+
+O_CLOEXEC is introduced from Linux 2.6.23, so old kernel doesn't have
+it, we need check before use.
+
+This patch is much more like a workaround, since it may need fcntl() use
+FD_CLOEXEC to replace.
+
+This problem was reported by "Ting Liu <b28495@freescale.com>"
+
+[Thomas De Schampheleire <thomas.de.schampheleire@gmail.com:
+ - move dummy definition from libkmod-internal.h to missing.h
+ - update commit title]
+
+[Vicente: Adapt this patch to version 19.]
