-Subject: [PATCH] Linux 3.12 compat: New shrinker API
-
-torvalds/linux@24f7c6 introduced a new shrinker API while
-torvalds/linux@a0b021 dropped support for the old shrinker API.
-This patch adds support for the new shrinker API by wrapping
-the old one with the new one.
-
-This change also reorganizes the autotools checks on the shrinker
-API such that the configure script will fail early if an unknown
-API is encountered in the future.
-
-Support for the set_shrinker() API which was used by Linux 2.6.22
-and older has been dropped.  As a general rule compatibility is
-only maintained back to Linux 2.6.26.

-- * Linux 2.6. - 2.6. Shrinker API Compatibility.
-+ * Due to frequent changes in the shrinker API the following
-+ * compatibility wrappers should be used.  They are as follows:
-+ *
-+ * SPL_SHRINKER_DECLARE is used to declare the shrinker which is
-+ * passed to spl_register_shrinker()/spl_unregister_shrinker().  Use
-+ * shrinker_name to set the shrinker variable name, shrinker_callback
-+ * to set the callback function, and seek_cost to define the cost of
-+ * reclaiming an object.
-+ *
-+ *   SPL_SHRINKER_DECLARE(shrinker_name, shrinker_callback, seek_cost);
-+ *
-+ * SPL_SHRINKER_CALLBACK_FWD_DECLARE is used when a forward declaration
-+ * of the shrinker callback function is required.  Only the callback
-+ * function needs to be passed.
-+ *
-+ *   SPL_SHRINKER_CALLBACK_FWD_DECLARE(shrinker_callback);
-+ *
-+ * SPL_SHRINKER_CALLBACK_WRAPPER is used to declare the callback function
-+ * which is registered with the shrinker.  This function will call your
-+ * custom shrinker which must use the following prototype.  Notice the
-+ * leading __'s, these must be appended to the callback_function name.
-+ *
-+ *   int  __shrinker_callback(struct shrinker *, struct shrink_control *)
-+ *   SPL_SHRINKER_CALLBACK_WRAPPER(shrinker_callback);a
-+ *
-+ *
-+ * Example:
-+ *
-+ * SPL_SHRINKER_CALLBACK_FWD_DECLARE(my_shrinker_fn);
-+ * SPL_SHRINKER_DECLARE(my_shrinker, my_shrinker_fn, 1);
-+ *
-+ * static int
-+ * __my_shrinker_fn(struct shrinker *shrink, struct shrink_control *sc)
-+ * {
-+ *	if (sc->nr_to_scan) {
-+ *		...scan objects in the cache and reclaim them...
-+ *	}
-+ *
-+ *	...calculate number of objects in the cache...
-+ *
-+ *	return (number of objects in the cache);
-+ * }

-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.
