函数名称:get_mctgt_type - get target type of moving charge*@vma: the vma the pte to be checked belongs*@addr: the address corresponding to the pte to be checked*@ptent: the pte to be checked*@target: the pointer the target page or swap ent will be stored(can be
函数原型:static enum mc_target_type get_mctgt_type(struct vm_area_struct *vma, unsigned long addr, pte_t ptent, union mc_target *target)
返回类型:enum mc_target_type
参数:
类型 | 参数 | 名称 |
---|---|---|
struct vm_area_struct * | vma | |
unsigned long | addr | |
pte_t | ptent | |
union mc_target * | target |
5400 | ret等于MC_TARGET_NONE |
5401 | swp_entry_t ent = {val = 0} |
5403 | 如果pte_present(ptent)则page等于mc_handle_present_pte(vma, addr, ptent) |
5405 | 否则如果heck whether a pte points to a swap entry 则page等于mc_handle_swap_pte(vma, ptent, & ent) |
5412 | 如果page则 |
5418 | 如果mem_cgroup恒等于from则 |
5419 | ret等于MC_TARGET_PAGE |
5420 | 如果is_device_private_page(page)则ret等于MC_TARGET_DEVICE |
5434 | ret等于MC_TARGET_SWAP |
5438 | 返回:ret |
