1 Using swap files with software suspend (swsusp)
4 The Linux kernel handles swap files almost in the same way as it handles swap
5 partitions and there are only two differences between these two types of swap
7 (1) swap files need not be contiguous,
8 (2) the header of a swap file is not in the first block of the partition that
10 already taken care of by the swap-handling code, but (2) has to be taken into
13 In principle the location of a swap file's header may be determined with the
15 filesystem holding the swap file to be mounted, and if this filesystem is
17 identify a swap file swsusp uses the name of the partition that holds the file
18 and the offset from the beginning of the partition at which the swap file's
22 In order to use a swap file with swsusp, you need to:
24 1) Create the swap file and make it active, eg.
30 2) Use an application that will bmap the swap file with the help of the
31 FIBMAP ioctl and determine the location of the file's swap header, as the
33 holds the swap file.
39 where <swap_file_partition> is the partition on which the swap file is located
40 and <swap_file_offset> is the offset of the swap header determined by the
42 by the same application that determines the swap file's header offset using the

53 Now, swsusp will use the swap file in the same way in which it would use a swap
54 partition.  In particular, the swap file has to be active (ie. be present in
57 Note that if the swap file used for suspending is deleted and recreated,
