When direct reclaim encounters a dirty page, it gets recycled around
the LRU for another cycle. This patch marks the page PageReclaim
similar to deactivate_page() so that the page gets reclaimed almost
immediately after the page gets cleaned. This is to avoid reclaiming
clean pages that are younger than a dirty page encountered at the
end of the LRU that might have been something like a use-once page.

Apart from the naming of the counter (I like nr_reclaim_preferred),

At the moment it's NR_VMSCAN_IMMEDIATE and the name visible in
/proc/vmstat is nr_vmscan_immediate_reclaim
