From 04bb171e7aa99dee0c92e772e4f66f8d5c1b4081 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 6 Nov 2014 14:36:43 +0000 Subject: kdb: Use KDB_REPEAT_* values as flags The actual values of KDB_REPEAT_* enum values and overall logic stayed the same, but we now treat the values as flags. This makes it possible to add other flags and combine them, plus makes the code a lot simpler and shorter. But functionality-wise, there should be no changes.
