函数名称：heck_move_unevictable_pages - check pages for evictability and move to* appropriate zone lru list*@pvec: pagevec with lru pages to check* Checks pages for evictability, if an evictable page is in the unevictable

函数原型：void check_move_unevictable_pages(struct pagevec *pvec)

返回类型：void

参数：

类型参数名称
struct pagevec *pvec
4333  struct pglist_data * pgdat = NULL
4334  pgscanned等于0
4335  pgrescued等于0
4338  以i小于nr循环
4339  page等于pages[i]
4340  pagepgdat等于page_pgdat(page)
4342  pgscanned自加
4343  如果pagepgdat不等于pgdat则
4344  如果pgdat则spin_unlock_irq( & Write-intensive fields used by page reclaim )
4346  pgdat等于pagepgdat
4347  spin_lock_irq( & Write-intensive fields used by page reclaim )
4349  lruvec等于mem_cgroup_page_lruvec(page, pgdat)
4351  如果非PageLRU(page)或非PageUnevictable(page)则继续下一循环
4354  如果page_evictable - test whether a page is evictable*@page: the page to test* Test whether page is evictable--i则
4355  lru等于page_lru_base_type - which LRU list type should a page be on?*@page: the page to test* Used for LRU list index arithmetic.* Returns the base LRU type - file or anon - @page should be on.
4357  VM_BUG_ON_PAGE(PageActive(page), page)
4358  ClearPageUnevictable(page)
4359  del_page_from_lru_list(page, lruvec, LRU_UNEVICTABLE)
4360  add_page_to_lru_list(page, lruvec, lru)
4361  pgrescued自加
4365  如果pgdat则
4366  __count_vm_events( rescued from noreclaim list , pgrescued)
4367  __count_vm_events( scanned for reclaimability , pgscanned)
4368  spin_unlock_irq( & Write-intensive fields used by page reclaim )
