Commit Message

  Commit dd06e72e68bc ("Compiler Attributes: Add __counted_by macro")
added __counted_by() annotation.  The underlying attribute for the
feature is still under development, but adopting it can improve the
readability of the code.  Apply it to four dynamic arrays in DAMON sysfs
code.
