Significantly higher memory usage in kernel 6.17

6.16

Slab:            1320136 kB
SReclaimable:      62752 kB
SUnreclaim:      1257384 kB

6.17

Slab:            2299328 kB
SReclaimable:      51848 kB
SUnreclaim:      2247480 kB

6.17 with apparmor disabled:

Slab:             161572 kB
SReclaimable:      53100 kB
SUnreclaim:       108472 kB

This is Arch Linux, right now I had to remove more than 1k profiles to reduce the ram usage by kernel and 6.17 still consumes more memory than 6.16 (~900MB vs 500MB)
I'm posting this as a heads-up but also in case someone much more capable than me can provide an explanation or report the issue to the kernel

I managed to greatly reduce apparmor runtime memory by disabling CONFIG_SECURITY_APPARMOR_INTROSPECT_POLICY in 6.18 kernel. This is enabled in arch's kernel.
It was reduced by half, just like it was in 6.16
