Remove valueless definition of hard-selected RAMFS option (8e3f715a) · Commits · 戴 / test

Since CONFIG_RAMFS is currently hard-selected to "y", and since Documentation/filesystems/ramfs-rootfs-initramfs.txt reads as follows: "The amount of code required to implement ramfs is tiny, because all the work is done by the existing Linux caching infrastructure. Basically, you're mounting the disk cache as a filesystem. Because of this, ramfs is not an optional component removable via menuconfig, since there would be negligible space savings." It seems pointless to leave this as a Kconfig entry. Signed-off-by:

		Ramfs is a file system which keeps all files in RAM. It allows
		read and write access.

		It is more of an programming example than a useable file system. If
		you need a file system which lives in RAM with limit checking use
		tmpfs.

		To compile this as a module, choose M here: the module will be called
		ramfs.
