Per our discussion tonight, lets keep CONFIG_ACPI_PROCFS. We just changed it to default to =n in 2.6.36, and even that caused complaints -- so there are still users out there of /proc/acpi/batter, even though /sys/class/power_supply shipped in 2007. In 2.6.38, lets add it to feature-removal.txt, say for a year from now, and add a (single) run-time warning on access. thanks, -Len > Sign-off-by: Zhang Rui <rui.zhang@xxxxxxxxx> > --- > drivers/acpi/Kconfig | 15 --------------- > drivers/acpi/Makefile | 2 +- > drivers/acpi/ac.c | 20 ++++++++++---------- > drivers/acpi/battery.c | 20 ++++++++++---------- > drivers/acpi/sbs.c | 20 ++++++++++---------- > 5 files changed, 31 insertions(+), 46 deletions(-) > > Index: linux-2.6/drivers/acpi/Kconfig > =================================================================== > --- linux-2.6.orig/drivers/acpi/Kconfig > +++ linux-2.6/drivers/acpi/Kconfig > @@ -62,21 +62,6 @@ config ACPI_PROCFS > > Say N to delete /proc/acpi/ files that have moved to /sys/ > > -config ACPI_PROCFS_POWER > - bool "Deprecated power /proc/acpi directories" > - depends on PROC_FS > - help > - For backwards compatibility, this option allows > - deprecated power /proc/acpi/ directories to exist, even when > - they have been replaced by functions in /sys. > - The deprecated directories (and their replacements) include: > - /proc/acpi/battery/* (/sys/class/power_supply/*) > - /proc/acpi/ac_adapter/* (sys/class/power_supply/*) > - This option has no effect on /proc/acpi/ directories > - and functions, which do not yet exist in /sys > - > - Say N to delete power /proc/acpi/ directories that have moved to /sys/ > - > config ACPI_POWER_METER > tristate "ACPI 4.0 power meter" > depends on HWMON -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
