These functions are either coded in individual files as static or not used at all. Remove them.

PATCH 1/1 ocfs2: Code cleanup: Removed unused functions

Hi Goldwyn,

I am not 100% sure ... but my understanding is ocfs2_fs.h defines metadata structures and helper functions. This file is shared between ocfs2-tools and kernel modules. The functions you mentioned are used by ocfs2-tools code and hence exist in this file.

Thanks,
--Srini

Yes. However, these functions should be a part of
ocfs2-tools/include/ocfs2.h. Isn't it?
