+++ This bug was initially created as a clone of Bug #236624 +++ When checking the sync status of a region, there are times when we must not block. Like when we are attempting to map I/O for the first time or in a context that must not block. do_reads operates in a separate kernel thread and should be allowed to block. [Disallowing it to do so means cluster mirroring can never read-balance, among other things.]
