Subject: selftests/damon/_damon_sysfs: implement updat_schemes_tried_bytes command
Date: Tue, 12 Dec 2023 19:48:08 +0000
Implement update_schemes_tried_bytes command of DAMON sysfs interface in
_damon_sysfs.py. It is not only making the update, but also read the
updated value from the sysfs interface and store it in the Kdamond python
objects so that the user of the module can easily get the value.
