Suspend writes in RAID1 if within range
If there is a resync going on, all nodes must suspend writes to the range. This is recorded in the suspend_info/suspend_list. If there is an I/O within the ranges of any of the suspend_info, should_suspend will return 1. Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com>
