+Subject: [PATCH 1/3] FreeBSD port
+
+- deal with lack of dirent.d_off on FreeBSD
+- make xattr* functions essentially no-ops
+- skip prctl() and setrlimit()
+- some differences in struct statfs
+- some mount options lacking
+- replace SOL_TCP by IPPROTO_TCP
+- use linux value for errno EOPNOTSUPP

+Subject: [PATCH 2/3] diod/ops.c: add header file for makedev
+
+Error:
+diod/ops.c:845: undefined reference to `makedev'
+
+Fixed:
+Glibc removes sys/sysmacros.h which defines makedev from sys/types.h
+since v2.28. [Commit ID: e16deca62e16f]
+
+And then glibc suggestions us to include <sys/sysmacros.h> directly if
+code needs it.

+Subject: [PATCH 3/3] Diod: Lua detection fix and replacing deprecated function
+
+lua_open was replaced with luaL_newstate, which succeeded it in Lua 5.2.
+lua_open was already deprecated in Lua 5.1.
+Also, in order to check for Lua during config, a test for luaL_newstate
+is used, which works for both Lua 5.1 and 5.2, instead of testing for
+lua_call, which does not work for Lua 5.2.
