Huang Shijie b72b71c6cb lib: do code optimization for radix_tree_lookup() and radix_tree_lookup_slot() ... radix_tree_lookup() and radix_tree_lookup_slot() have much the same code except for the return value. Introduce radix_tree_lookup_element() to do the real work. /* * is_slot == 1 : search for the slot. * is_slot == 0 : search for the node. */ static void * radix_tree_lookup_element(struct radix_tree_root *root, unsigned long index, int is_slot); Signed-off-by: Huang Shijie <shijie8@gmail.com> Cc: Nick Piggin <nickpiggin@yahoo.com.au> Cc: Christoph Lameter <cl@linux-foundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		16 years ago
