One possible idea would be to use strscpy() instead and directly assign
the return value to sz, avoiding an extra strl
This patch supports new feature "zram idle/huge page writeback".
On zram-swap usecase, zram has usually many idle/huge swap pages.
It's pointless to keep in memory(ie, zram).
To solve the problem, this feature introduces idle/huge page
writeback to backing device so the goal is to save more memory
