函数名称：always: directly stall for all thp allocations* defer: wake kswapd and fail if not immediately available* defer+madvise: wake kswapd and directly stall for MADV_HUGEPAGE, otherwise* fail if not immediately available* madvise: directly stall for
函数原型：static inline gfp_t alloc_hugepage_direct_gfpmask(struct vm_area_struct *vma)
返回类型：gfp_t
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| struct vm_area_struct * | vma |
| 666 | vma_madvised等于非非Flags, see mm.h. 按位与MADV_HUGEPAGE marked this vma 的值 |
| 669 | 如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:GFP_TRANSHUGE按位或如果vma_madvised则0否则__GFP_NORETRY |
| 673 | 如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:GFP_TRANSHUGE_LIGHT按位或kswapd can wake |
| 677 | 如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:GFP_TRANSHUGE_LIGHT按位或如果vma_madvised则Caller can reclaim 否则kswapd can wake |
| 683 | 如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:GFP_TRANSHUGE_LIGHT按位或如果vma_madvised则Caller can reclaim 否则0 |
