X-Git-Tag: v2.6.28-rc1~572^2~27 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a09f556e5415a29cdddaf9a6ebf474194161cf3;p=pandora-kernel.git ocfs2: Create specific get_extent_tree functions. A caller knows what kind of extent tree they have. There's no reason they have to call ocfs2_get_extent_tree() with a NULL when they could just as easily call a specific function to their type of extent tree. Introduce ocfs2_dinode_get_extent_tree(), ocfs2_xattr_tree_get_extent_tree(), and ocfs2_xattr_value_get_extent_tree(). They only take the necessary arguments, calling into the underlying __ocfs2_get_extent_tree() to do the real work. __ocfs2_get_extent_tree() is the old ocfs2_get_extent_tree(), but without needing any switch-by-type logic. ocfs2_get_extent_tree() is now a wrapper around the specific calls. It exists because a couple alloc.c functions can take et_type. This will go later. Another benefit is that ocfs2_xattr_value_get_extent_tree() can take a struct ocfs2_xattr_value_root* instead of void*. This gives us typechecking where we didn't have it before.
