Ohk, I did some more search and found this... sharing for newbies like me.
The kernel source tree... Even the just the modules directory reflects some of that. ls /lib64/modules/2.6.27-14-generic/kernel/ arch crypto drivers fs lib net sound ubuntu ls /lib64/modules/2.6.27-14-generic/kernel/drivers/ acpi auxdisplay cdrom crypto edac gpu i2c input md mfd mtd pci rtc spi uio virtio ata block char dca firmware hid ieee1394 isdn media misc net pcmcia scsi ssb usb w1 atm bluetooth cpufreq dma gpio hwmon infiniband leds message mmc parport power serial telephony video watchdog

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.

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. Best regards Sekar
