Subject: samples/damon/wsse: avoid starting DAMON before initialization
Date: Mon, 8 Sep 2025 19:22:36 -0700

Patch series "samples/damon: fix boot time enable handling fixup merge mistakes".

First three patches of the patch series "mm/damon: fix misc bugs in DAMON modules" [1] were trying to fix boot time DAMON sample modules enabling issues. The issues are the modules can crash if those are enabled before DAMON is enabled, like using boot time parameter options. The three patches were fixing the issues by avoiding starting DAMON before the module initialization phase.

However, probably by a mistake during a merge, only half of the change is merged, and the part for avoiding the starting of DAMON before the module initialized is missed. So the problem is not solved and thus the modules can still crash if enabled before DAMON is initialized. Fix those by applying the unmerged parts again.

Note that the broken commits are merged into 6.17-rc1, but also backported to relevant stable kernels. So this series also needs to be merged into the stable kernels. Hence Cc-ing stable@.

This patch (of 3):

Commit 0ed1165c3727 ("samples/damon/wsse: fix boot time enable handling") is somehow incompletely applying the origin patch [2]. It is missing the part that avoids starting DAMON before module initialization. Probably a mistake during a merge has happened. Fix it by applying the missed part again.
