flags等于0

199

以i小于pagevec_count(pvec)循环

200

page等于pages[i]

201

pagepgdat等于page_pgdat(page)

如果pagepgdat不等于pgdat则

204

如果pgdat则spin_unlock_irqrestore( & Write-intensive fields used by page reclaim , flags)

206

pgdat等于pagepgdat

207

spin_lock_irqsave( & Write-intensive fields used by page reclaim , flags)

210

lruvec等于mem_cgroup_page_lruvec(page, pgdat)

211

( * move_fn)(page, lruvec, arg)

213

如果pgdat则spin_unlock_irqrestore( & Write-intensive fields used by page reclaim , flags)

**调用者**
名称	描述
pagevec_move_tail	pagevec_move_tail() must be called with IRQ disabled.* Otherwise this may cause nasty races.
lru_add_drain_cpu	Drain pages out of the cpu's pagevecs.* Either "cpu" is the current CPU, and preemption has already been* disabled; or "cpu" is being hot-unplugged, and is already dead.
deactivate_file_page	deactivate_file_page - forcefully deactivate a file page@page: page to deactivate This function hints the VM that @page is a good reclaim candidate,* for example if its invalidation fails due to the page being dirty* or under writeback.
deactivate_page	deactivate_page - deactivate a page@page: page to deactivate deactivate_page() moves @page to the inactive list if @page was on the active* list and was not an unevictable page. This is done to accelerate the reclaim* of @page.
mark_page_lazyfree	mark_page_lazyfree - make an anon page lazyfree@page: page to deactivate mark_page_lazyfree() moves @page to the inactive file list.* This is done to accelerate the reclaim of @page.
__pagevec_lru_add	Add the passed pages to the LRU, then drop the caller's refcount* on them. Reinitialises the caller's pagevec.
