b9d73218 - treewide: change conditional prompt for choices to 'depends on'

Wed, 26 Jun 2024 18:22:00 +0000

treewide: change conditional prompt for choices to 'depends on'While Documentation/kbuild/kconfig-language.rst provides a briefexplanation, there are recurring confusions regarding the usage of aprompt followed by 'if '. This conditional controls _only_ theprompt.A typical usage is as follows: menuconfig BLOCK bool "Enable the block layer" if EXPERT default yWhen EXPERT=n, the prompt is hidden, but this config entry is stillactive, and BLOCK is set to its default value 'y'. This is reasonablebecause you are likely want to enable the block device support. WhenEXPERT=y, the prompt is shown, allowing you to toggle BLOCK.Please note that it is different from 'depends on EXPERT', which wouldenable 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, thechoice 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" endchoiceI believe the first case should hide only the prompt, producing thedefault: CONFIG_A=y # CONFIG_B is not setThe next commit will change (fix) the behavior of the conditional promptin 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_3GThis 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 convertedit to 'depends on' to avoid any potential behavioral change.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/fs/jffs2/Kconfig

fs/*/Kconfig: drop links to 404-compliant http://acl.bestbits.atThis link is replicated in most filesystems' config stanzas.

cf98c5e5 - fs/jffs2: remove depends on CONFIG_EXPERIMENTAL

Thu, 17 Jan 2013 02:54:12 +0000

fs/jffs2: remove depends on CONFIG_EXPERIMENTALThe CONFIG_EXPERIMENTAL config item has not carried much meaning for awhile now and is almost always enabled by default. As agreed during theLinux kernel summit, remove it from any "depends on" lines in Kconfigs.CC: David Woodhouse Cc: Al Viro Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/fs/jffs2/Kconfig
