[Ocfs2-devel] [PATCH] ocfs2: Code cleanup: Removed unused functions

[Srinivas Eeda]

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
