상세한 설명

template<class Locker>
class LockedPageManagerBase< Locker >

Thread-safe class to keep track of locked (ie, non-swappable) memory pages.

Memory locks do not stack, that is, pages which have been locked several times by calls to mlock() will be unlocked by a single call to munlock(). This can result in keying material ending up in swap when those functions are used naively. This class simulates stacking memory locks by keeping a counter per page.

주의

By using a map from each page base address to lock count, this class is optimized for small objects that span up to a few pages, mostly smaller than a page. To support large allocations, something like an interval tree would be the preferred data structure.
