+Subject: [PATCH] Update struct member intializers to C89
+
+When building SPL within the kernel tree, C99 initializers cause
+build failures and need to be converted to C89 as kernel CFLAGS
+specify -std=gnu89.
+
+This fix was provided by @behlendorf in #595 discussion notes and
+manually implemented in the current master revision.
+
+Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov>
+Signed-off-by: RageLtMan <rageltman@sempervictus>
+Closes #597
