# Test that if we punch a hole in a file, with either a range that goes beyond
# the file's size or covers a file range that is already a hole, and that if
# after we do some buffered write operations that cover different parts of the
# hole, no warnings are emmitted in syslog/dmesg and the file's content is
# correct after remounting the filesystem.
