[PATCH 3/8] mm/damon/paddr,vaddr: Register themselves to DAMON in subsys_initcall

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit makes the monitoring operations for the physical address
space and virtual address spaces register themselves to DAMON in the
subsys_initcall step.  Later, in-kernel DAMON user code can use them via
damon_select_ops() without have to unnecessarily depend on all possible
monitoring operations implementations.
