mainline inclusion from mainline-v6.7-rc1 commit 3dfbb555c98ac55b9d911f9af0e35014b445fb41 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9O1OT CVE: NA

--------------------------------
This isolate_mode_t flag is effectively unused since 89f6c88a6ab4 ("mm: __isolate_lru_page_prepare() in isolate_migratepages_block()") as sc->may_unmap is now checked directly (and only node_reclaim has a mode that sets it to 0). The last remaining place is mm_vmscan_lru_isolate tracepoint for the isolate_mode parameter. That one was mainly used to indicate the active/inactive mode, which the trace-vmscan-postprocess.pl script consumed, but that got silently broken. After fixing the script by the previous patch, it does not need the isolate_mode anymore. So just remove the parameter and with that the whole ISOLATE_UNMAPPED flag.

You should use 'git cherry-pick', this should no fail with cherry-pick :)
