+Subject: [PATCH 1/2] yaffs: Replace yaffs_dir_llseek with Linux generic
+ llseek
+
+commit ed8188fb7659cfb65b5adbe154d143190ade0324 upstream.
+
+There was not much point in having the yaffs version as it is
+functionally equivalent to the kernel one.
+
+This also gets rid of using BKL in yaffs2.

+Date: Tue, 30 Nov 2010 16:01:28 +1300
+Subject: [PATCH 1/2] yaffs: Replace yaffs_dir_llseek with Linux generic
+ llseek
+
+commit ed8188fb7659cfb65b5adbe154d143190ade0324 upstream.
+
+There was not much point in having the yaffs version as it is
+functionally equivalent to the kernel one.
+
+This also gets rid of using BKL in yaffs2.
+
