rcu: move PREEMPT_RCU config option back under PREEMPT

2008-03-11T01:01:20Z

The original preemptible-RCU patch put the choice between classic and preemptible RCU into kernel/Kconfig.preempt, which resulted in build failures on machines not supporting CONFIG_PREEMPT. This choice was therefore moved to init/Kconfig, which worked, but placed the choice between classic and preemptible RCU at the top level, a very obtuse choice indeed. This patch changes from the Kconfig "choice" mechanism to a pair of booleans, only one of which (CONFIG_PREEMPT_RCU) is user-visible, and is located in kernel/Kconfig.preempt, where one would expect it to be. The other (CONFIG_CLASSIC_RCU) is in init/Kconfig so that it is available to all architectures, hopefully avoiding build breakage. Thanks to Roman Zippel for suggesting this approach.

Group together the config options for Resource Counters and Memory Resource Controller. Signed-off-by: Balbir Singh Cc: Paul Menage Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sysfs: CONFIG_SYSFS_DEPRECATED fix

2008-03-04T22:47:04Z

CONFIG_SYSFS_DEPRECATED=y changed its meaning recently and causes regressions in working setups that had SYSFS_DEPRECATED disabled. so rename it to SYSFS_DEPRECATED_V2 so that testers pick up the new default via 'make oldconfig', even if their old .config's disabled CONFIG_SYSFS_DEPRECATED ...

driver core: fix up Kconfig text for CONFIG_SYSFS_DEPRECATED

2008-03-04T22:47:04Z

As things get moved into this config option, the hard date of 2006 does not work anymore, so update the text to be more descriptive. Cc: Kay Sievers Cc: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

cgroup memory controller: document huge memory/cache overhead in Kconfig

2008-02-24T01:12:16Z

Document huge memory/cache overhead of memory controller in Kconfig I was a little surprised that 2.6.25-rc* increased struct page for the memory controller. At least on many x86-64 machines it will not fit into a single cache line now anymore and also costs considerable amounts of RAM. At earlier review I remembered asking for a external data structure for this. It's also quite unobvious that a innocent looking Kconfig option with a single line Kconfig description has such a negative effect. This patch attempts to document these disadvantages at least so that users configuring their kernel can make a informed decision.

namespaces: cleanup the code managed with PID_NS option

2008-02-08T17:22:23Z

Just like with the user namespaces, move the namespace management code into the separate .c file and mark the (already existing) PID_NS option as "depend on NAMESPACES" [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Pavel Emelyanov Acked-by: Serge Hallyn Cc: Cedric Le Goater Cc: "Eric W.

namespaces: cleanup the code managed with the USER_NS option

2008-02-08T17:22:23Z

Make the user_namespace.o compilation depend on this option and move the init_user_ns into user.c file to make the kernel compile and work without the namespaces support. This make the user namespace code be organized similar to other namespaces'. Also mask the USER_NS option as "depend on NAMESPACES".
