Hi all, After merging the cgroup tree, today's linux-next build (x86_64 allmodconfig) failed like this: kernel/cgroup/cgroup.c:5275:26: error: 'CFTYPE_PRESSURE' undeclared here (not in a function) 5275 | .flags = CFTYPE_PRESSURE, | ^~~~~~~~~~~~~~~ Caused by commit 8a693f7766f9 ("cgroup: Remove CFTYPE_PRESSURE") inteacting with commits 52b1364ba0b1 ("sched/psi: Add PSI_IRQ to track IRQ/SOFTIRQ pressure") 34f26a15611a ("sched/psi: Per-cgroup PSI accounting disable/re-enable interface") from the tip tree. I have applied the following merge fix patch.
