From b9d73218d78778effd2924664ed93d78ff6949de Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 27 Jun 2024 03:22:00 +0900 Subject: treewide: change conditional prompt for choices to 'depends on' While Documentation/kbuild/kconfig-language.rst provides a brief explanation, there are recurring confusions regarding the usage of a prompt followed by 'if '. This conditional controls _only_ the prompt. A typical usage is as follows: menuconfig BLOCK bool "Enable the block layer" if EXPERT default y When EXPERT=n, the prompt is hidden, but this config entry is still active, and BLOCK is set to its default value 'y'. This is reasonable because you are likely want to enable the block device support. When EXPERT=y, the prompt is shown, allowing you to toggle BLOCK. Please note that it is different from 'depends on EXPERT', which would enable and disable the entire config entry. However, this conditional prompt has never worked in a choice block. The following two work in the same way: when EXPERT is disabled, the choice block is entirely disabled. [Test Code 1] choice prompt "choose" if EXPERT config A bool "A" config B bool "B" endchoice [Test Code 2] choice prompt "choose" depends on EXPERT config A bool "A" config B bool "B" endchoice I believe the first case should hide only the prompt, producing the default: CONFIG_A=y # CONFIG_B is not set The next commit will change (fix) the behavior of the conditional prompt in choice blocks. I see several choice blocks wrongly using a conditional prompt, where 'depends on' makes more sense. To preserve the current behavior, this commit converts such misuses. I did not touch the following entry in arch/x86/Kconfig: choice prompt "Memory split" if EXPERT default VMSPLIT_3G This is truly the correct use of the conditional prompt; when EXPERT=n, this choice block should silently select the reasonable VMSPLIT_3G, although the resulting PAGE_OFFSET will not be affected anyway. Presumably, the one in fs/jffs2/Kconfig is also correct, but I converted it to 'depends on' to avoid any potential behavioral change.

Before this, make will still continue to succeed even after the installation failed, for example, for insufficient permission or directory does not exist.
