Hi, the regression started from 6.5.3, i failed to mention it in bugzilla.
Original I made ticket on linux-zen, thinking it was their problem. But it turned out to be problem from normal linux itself.

Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
> Since 1st weak of Sept I have been observing memory leak in my system, so after doing a little big of digging I found out that the leak is caused by kmalloc. In Linux 6.5.3 memory leak would increase to nearly 50% of my ram over a period of 6-9 hours. In the Newer Linux 6.5.4 I am yet to observe that much memory leak(Haven't used my laptop for that long till now) but over a period of 3 hours I see 2.2GB reserved and it is not used by any program at all. this is just after 3 hours of usage on Linux 6.5.4.
Later, the reporter (Cc'ed) narrowed down the version range, with
memory statistics:

See Bugzilla for the full thread.
Anyway, I'm adding this regression to be tracked by regzbot:
#regzbot introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217943
Thanks.
