list of all subsystems (swap space)

[inventsekar]

Hi All,

1. so I tried to find out which subsystem the swap space comes under..
when I googled for list of subsystems Linux architecture, no luck.
Between, I found out that kernel map (
http://www.makelinux.net/kernel_map/ ), which gives me kind of
subsystems/modules.

Is there any documentation/links for list of subsystems on Linux?!?!

2. it looks like swap space itself a separate subsystem/module.
I thought to subscribe to some lkml dl for swap, but I am not finding any
DL at all. Please suggest.


Best regards
Sekar

Hi All,
I have been reading about swap space and got  these questions...

1. Btrfs was the only one fs which got this below issue or any other fs
also?
2. The other way around - is there any FS which is best suitable (best
performance) for swap file?
2. Is this issue still there or the wiki isn't updated?

*https://wiki.archlinux.org/index.php/swap
<https://wiki.archlinux.org/index.php/swap>*
*Warning:* Btrfs <https://wiki.archlinux.org/index.php/Btrfs> does not
support swap files. Failure to heed this warning may result in file system
corruption. While a swap file may be used on Btrfs when mounted through a
loop device, this will result in severely degraded swap performance.

Any suggestions, links, documentations please.
