when reclaiming pages from an image, always reclaim all the hash chains equally. that way, we avoid being biased towards the chains at the start of the Image.pghash[] array. images can be in two states: active or inactive. inactive images are the ones which are not used by program while active ones aare. when reclaiming pages, we should try to reclaim pages from inactive images first and only if that set becomes exhausted attempt to release text pages and attempt to reclaim pages from active images. when we run out of Image structures, it makes only sense to reclaim pages from inactive images, as reclaiming pages from active ones will never free any Image structures. change putimage() to require a image already locked and make it unlock the image. this avoids many pointless unlock()/lock() sequences as all callers of putimage() already had the image locked. |
