memory_bm_next

函数名称：memory_bm_rtree_next_pfn - Find the next set bit in a memory bitmap.*@bm: Memory bitmap.* Starting from the last returned position this function searches for the next* set bit in @bm and returns the PFN represented by it. If no more bits are

函数原型：static unsigned long memory_bm_next_pfn(struct memory_bitmap *bm)

返回类型：unsigned long

struct memory_bitmap *	bm

**调用者**
名称	描述
clear_free_pages
copy_data_pages
swsusp_free	swsusp_free - Free pages allocated for hibernation image.* Image pages are alocated before snapshot creation, so they need to be* released after resume.
free_unnecessary_pages	_unnecessary_pages - Release preallocated pages not needed for the image.
pack_pfns	pack_pfns - Prepare PFNs for saving.@bm: Memory bitmap.@buf: Memory buffer to store the PFNs in.* PFNs corresponding to set bits in @bm are stored in the area of memory* pointed to by @buf (1 page at a time).
snapshot_read_next	snapshot_read_next - Get the address to read the next image page from.@handle: Snapshot handle to be used for the reading. On the first call, @handle should point to a zeroed snapshot_handle* structure
duplicate_memory_bitmap
mark_unsafe_pages	mark_unsafe_pages - Mark pages that were used before hibernation.* Mark the pages that cannot be used for storing the image during restoration,* because they conflict with the pages that had been used before hibernation.
get_buffer	get_buffer - Get the address to store the next image data page.* Get the address that snapshot_write_next() should return to its caller to* write to.
