Hi, I want to increase my knowledge about the options we can choose when recompiling the kernel. I have already encountered some doubts just starting: Support for paging of anonymous memory (swap) (SWAP) This option allows you to choose whether you want to have support for socalled swap devices or swap files in your kernel that are used to provide more virtual memory than the actual RAM present in your computer. If unsure say Y. What king of swap devices or files makes this option reference to? I get the following error recompiling if I disable it: kernel/built-in.o(.text+0x179d): In function `mmput': : undefined reference to `put_swap_token' mm/built-in.o(.text+0xfc8): In function `filemap_nopage': : undefined reference to `grab_swap_token' mm/built-in.o(.text+0xe658): In function `page_referenced_one': : undefined reference to `has_swap_token' make: *** [.tmp_vmlinux1] Error 1 [root@kalimotxo linux-2.6.8-1.521]# I thought that defining the swap filesystem and mounting it with swapon was enough.
