But could you re-send this one and the other one at http://patchwork.ozlabs.org/patch/84887/ : - with appropriate Signed-off-by: and changelog for the other patch - using a const size_t width = ds_get_width(vs->ds) / 16; in both patchs to make the call more explicit Thanks,

This patch fix the following two regressions: 1. we should use bitmap_set() and bitmap_clear() to replace vnc_set_bits(). 2. The unit of bitmap_intersects()'third parameter is bit, not words. But we pass the num of words to bitmap_intersects(). Changes from v1 to v2: 1. fix the third argument of bitmap_clear() Signed-off-by: Wen Congyang <wency@cn.fujitsu.com> --- ui/vnc.c | 9 +++++++-- 1 files changed, 7 insertions(+), 2 deletions(-)
