Some tests don't have x permission set in mode, git complains about
file mode change after running tests in fstests git repo dir. So
change all such tests to 755 mode. Performed by:
find tests ! -perm /111 -name [0-9][0-9][0-9] -exec chmod 755 {} \;

Add test which spawns two processes both writing one file via mmap.
Then to the test when processes first prefault the file by reading it
via mmap. This is mainly interesting to uncover races in DAX fault
handling.
