+Subject: [PATCH] Linux 3.13 compat: Pass NULL for new delegated inode argument
+
+This check was originally added for SLES10, a093c6a, to check for
+a 'struct vfsmount *' argument which they added. However, since
+SLES10 is based on a 2.6.16 kernel which is no longer supported
+this functionality was dropped. The checks were refactored to
+support Linux 3.13 without concern for historical versions.

+Subject: [PATCH] Linux 3.13 compat: Remove unused flags variable from
+ __cv_init()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GCC 4.8.1 complained about an unused flags variable when building
+against Linux 2.6.26.8:
+
+/var/tmp/portage/sys-kernel/spl-9999/work/spl-9999/module/spl/../../module/spl/spl-condvar.c:
+In function ‘__cv_init’:
+/var/tmp/portage/sys-kernel/spl-9999/work/spl-9999/module/spl/../../module/spl/spl-condvar.c:39:6:
+error: variable ‘flags’ set but not used
+[-Werror=unused-but-set-variable]
+ int flags = KM_SLEEP;
+ ^
+ cc1: all warnings being treated as errors
+
+Additionally, the superfluous code uses a preempt_count variable that is
+no longer available on Linux 3.13. Deleting the unnecessary code fixes a
+Linux 3.13 compatibility issue.
