From: Maxime Ripard <mripard@kernel.org> mainline inclusion from mainline-v6.14-rc1 commit feb85972b82c9747ebb0843f91e4c1e023b47f3d category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8422 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- During the dmem cgroup development, the parameters to the dmem_cgroup_state_evict_valuable() and dmem_cgroup_try_charge() were changed, but the documentation wasn't adjusted accordingly. This results in a documentation build warning. Adjust the documentation to reflect what the final functions parameters are.
