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.
