+Subject: md: Avoid namespace collision with bitmap API
+
+From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
+
+commit e64e4018d572710c44f42c923d4ac059f0a23320 upstream.
+
+bitmap API (include/linux/bitmap.h) has 'bitmap' prefix for its methods.
+
+On the other hand MD bitmap API is special case.
+Adding 'md' prefix to it to avoid name space collision.
+
+No functional changes intended.
