[Ocfs2-devel] [PATCH 3/4] Ocfs2: Make ocfs2_find_cpos_for_left_leaf() public.

[Tristan Ye <tristan.ye@oracle.com>]

The original idea to pull ocfs2_find_cpos_for_left_leaf() out of
alloc.c is to benefit punching-holes optimization patch, it however,
can also be referred by other funcs in the future who want to do the
same job.
