Subject: [PATCH] yaffs: Fix directory unlinking in yaffs1 mode
commit 964b3425a71890e6701c830e38b04d8557c04f49 upstream.
Treat both yaffs2 and yaffs1 paths the same.

Subject: [PATCH] yaffs: Switch from semaphores to mutexes
commit 73c54aa8c1de3f61a4c211cd47431293a6092f18 upstream.
Mutex is faster and init_MUTEX has been deprecated, so we'll just switch
to mutexes.

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.
