kernel: dm: don't attempt to queue IO under RCU protection

A sleep-in-atomic-context bug was found in the Device Mapper subsystem in the Linux kernel. When processing REQNOWAIT requests, dm incorrectly submits I/O while holding an RCU read lock, assuming that REQNOWAIT means no scheduling can occur. However, mempoolalloc and other allocation functions ma...
