Since INCFS_IOC_GET_FILLED_BLOCKS potentially leaks information about usage
patterns, and is only useful to someone filling the file, best protect it in
the same way as INCFS_IOC_FILL_BLOCKS.
Add useful field data_block_out as well
Test: incfs_test passes

When read log is 0 sized, we still need to init the wait queue to avoid
kernel panics if someone does decide to poll on the read log.
Test: Added test for this condition, incfs_test crashes
With fix, incfs_test doesn't crash

Filling blocks is not equivalent to writing a file, since they are
constrained by the root hash. selinux policy may wish to treat them
differently, for instance.

Move dnotify_test.c, Makefile, and .gitignore from Documentation/filesystems
to selftests/filesystems.
Remove filesystems build target from Documentation/Makefile and update
selftests/filesystems/Makefile to work under selftests. dnotify_test will
not be run as part of selftests suite and will not be included in install
targets. It can be built separately for now.
