Two test programs are added. The run time is about 1min on my el7 instance. The test script finishes up with a read/write mmap test on offline extents to verify the data wait paths in those functions. One program will perform vfs read/write and mmap read/write calls on the same file from across 5 threads (mounts) repeatedly. The goal is to assure there are no locking issues between read/write paths. The second test program performs consistency checking on a file that is repeatedly written/read using memory maps and normal reads and writes, and the content is verified after every operation.
