Name:swap_range_free
Proto:static void swap_range_free(struct swap_info_struct *si, unsigned long offset, unsigned int nr_entries)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct swap_info_struct * | si | |
unsigned long | offset | |
unsigned int | nr_entries |
705 | end = offset + nr_entries - 1 |
706 | void( * swap_slot_free_notify)(struct block_device * , unsigned long) |
708 | If offset < dex of first free in swap_map Then dex of first free in swap_map = offset |
710 | If end > dex of last free in swap_map Then |
711 | was_full = Not dex of last free in swap_map |
714 | If was_full && SWP_USED etc: see above & SWP_WRITEOK Then add_to_avail_list(si) |
717 | atomic_long_add(nr_entries, & nr_swap_pages) |
719 | If SWP_USED etc: see above & SWP_BLKDEV Then swap_slot_free_notify = swap_slot_free_notify |
722 | Else swap_slot_free_notify = NULL |
728 | offset++ |
