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(). Signed-off-by: Wen Congyang <wency@cn.fujitsu.com> --- ui/vnc.c | 8 ++++++-- 1 files changed, 6 insertions(+), 2 deletions(-)
