The patch titled Subject: mm: fix return type for functions nr_free_*_pages has been removed from the -mm tree. Its filename was mm-fix-return-type-for-functions-nr_free__pages.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Zhang Yanfei <zhangyanfei@xxxxxxxxxxxxxx> Subject: mm: fix return type for functions nr_free_*_pages Currently, the amount of RAM that functions nr_free_*_pages return is held in unsigned int. But in machines with big memory (exceeding 16TB), the amount may be incorrect because of overflow, so fix it.
