Re: regarding Swap

["Devvrat Tripathi" <tripathidevvrat@xxxxxxxxx>]

I dont exactly get the syscall swapon thing properly. Swap is supposed to be activated by the kernel right incase the main memory gets filled up. I dont understand how the kernel uses this system call as you cannot do system calls from kernel space or is there some daemon which is responsible to do this job.

swapon(2) system call, which calls sys_swapon() in mm/swapfile.c
