| |
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.

this also allows almost 300 "CONFIG_RAMFS=y" lines to be dropped from various defconfig files. and that horribly misleading Kconfig help text disappears as well. :-)
compile tested under i386.
