The patch titled Subject: mm/damon/paddr,vaddr: register themselves to DAMON in subsys_initcall has been added to the -mm tree. Its filename is mm-damon-paddrvaddr-register-themselves-to-damon-in-subsys_initcall.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/mm-damon-paddrvaddr-register-themselves-to-damon-in-subsys_initcall.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/mm-damon-paddrvaddr-register-themselves-to-damon-in-subsys_initcall.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: SeongJae Park <sj@xxxxxxxxxx> Subject: mm/damon/paddr,vaddr: register themselves to DAMON in subsys_initcall 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.
