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.

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.
