| H A D | alloc.h | diff 1a09f556e5415a29cdddaf9a6ebf474194161cf3 Wed Aug 20 19:44:24 CDT 2008 Joel Becker <joel.becker@oracle.com> 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.
