struct hstate * | h | |
long | delta |
3123 | spin_lock( & Protects updates to hugepage_freelists, hugepage_activelist, nr_huge_pages,* free_huge_pages, and surplus_huge_pages.) |
3141 | If delta > 0 Then |
3142 | If Increase the hugetlb pool such that it can accommodate a reservation* of size 'delta'. < 0 Then Go to out |
3145 | If delta > cpuset_mems_nr(free_huge_pages_node) Then |
3151 | ret = 0 |
3152 | If delta < 0 Then This routine has two main purposes:* 1) Decrement the reservation count (resv_huge_pages) by the value passed* in unused_resv_pages |
3155 | out : |
3156 | spin_unlock( & Protects updates to hugepage_freelists, hugepage_activelist, nr_huge_pages,* free_huge_pages, and surplus_huge_pages.) |
