Subject: ocfs2: Use struct ocfs2_extent_tree in ocfs2_num_free_extents().
X-Git-Tag: v2.6.28-rc1~572^2~29
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1c25d93a4a27c90c3ae33f9e724f7b67783d68d1;p=pandora-kernel.git

ocfs2: Use struct ocfs2_extent_tree in ocfs2_num_free_extents().

ocfs2_num_free_extents() re-implements the logic of
ocfs2_get_extent_tree().  Now that ocfs2_get_extent_tree() does not
allocate, let's use it in ocfs2_num_free_extents() to simplify the code.

The inode validation code in ocfs2_num_free_extents() is not needed.
All callers are passing in pre-validated inodes.
