242 idea of keeping mlock_count in Unevictable LRU list link field was revived and
319 __mlock_page().  __mlock_page() sets PageUnevictable, initializes mlock_count
321 mlock_count in place of LRU threading).  Or if the page was already PageLRU
322 and PageUnevictable and PageMlocked, it simply increments the mlock_count.
325 it may have been temporarily isolated from LRU.  In such cases the mlock_count
327 returns the page to "LRU".  Races prohibit mlock_count from being set to 1 then:
329 mlock_count on the low side, so that when munlocked the page will be rescued to
380 mlock_count, and when that reaches 0 it clears PageMlocked and clears
385 those cases its mlock_count field is unusable and must be assumed to be 0: so
411 before mlock_pte_range() reached it, it would get counted twice in mlock_count.
491 mlock_count, and when that reaches 0 it clears PageMlocked and clears
496 those cases its mlock_count field is unusable and must be assumed to be 0: so
517 and would not be counted out of mlock_count.  In this rare case, a page may
544      but events left mlock_count too low, so they were munlocked too early.
