H A Dswsusp-and-swap-files.rst2 Using swap files with software suspend (swsusp)
7 The Linux kernel handles swap files almost in the same way as it handles swap
8 partitions and there are only two differences between these two types of swap
10 (1) swap files need not be contiguous,
11 (2) the header of a swap file is not in the first block of the partition that
13 already taken care of by the swap-handling code, but (2) has to be taken into
16 In principle the location of a swap file's header may be determined with the
18 filesystem holding the swap file to be mounted, and if this filesystem is
20 identify a swap file swsusp uses the name of the partition that holds the file
21 and the offset from the beginning of the partition at which the swap file's

H A Dswap_numa.rst2 Automatically bind swap device to numa node
5 If the system has more than one swap device and swap device has the node
6 information, we can make use of this information to decide which swap
15 for swap devices. e.g. on a 2 node machine, assume 2 swap devices swapA and
22 Then node 0 will use the two swap devices in the order of swapA then swapB and
23 node 1 will use the two swap devices in the order of swapB then swapA. Note
26 A more complex example on a 4 node machine. Assume 6 swap devices are going to
29 The way to swap them on is the same as above::
42 swapA and swapB will be used in a round robin mode before any other swap device.

H A Dzswap.rst8 Zswap is a lightweight compressed cache for swap pages. It takes pages that are
11 for potentially reduced swap I/O. This trade-off can also result in a

23 * Users with SSDs as swap devices can extend the life of the device by
26 Zswap evicts pages from compressed cache on an LRU basis to the backing swap
45 pages out of the compressed pool, a swapoff on the swap device(s) will
