'charge' in this sentence is somewhat like 'charge a fee'.  I personally don't
feel it is weird.  But 'record' also work for me.

So this looks good to me, too.

If use of the term 'charge' is really making reading difficult, we could add a
short definition of 'charge' as a separate patch.

E.g., 

'''

 To mitigate that situation, DAMOS provides an upper-bound overhead control
 feature called quotas.  It lets users specify an upper limit of time that DAMOS
 can use for applying the action, and/or a maximum bytes of memory regions that

 To know how user-space can set the basic quotas via :ref:`DAMON sysfs interface

Please let me know if you'd like to send such a patch.

Sounds good.  But let's finish the discussion about use of the term, 'charge'
before posting v2.
