From 6d07859926fdb8515fd5cb94a692df7896c3848e Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 14 Jul 2016 16:33:22 +0300 Subject: [PATCH] dirty-bitmap: operate with int64_t amount Underlying HBitmap operates even with uint64_t. Thus this change is safe. This would be useful f.e. to mark entire bitmap dirty in one call. Signed-off-by: Denis V.
