* kernel: Map most files to use export.h instead of module.hPaul Gortmaker2011-10-311-1/+1
| | | | | | | | | | | | | | | | The changed files were only including linux/module.h for the EXPORT_SYMBOL infrastructure, and nothing else. Revector them onto the isolated export header for faster compile times. Nothing to see here but a whole lot of instances of: -#include <linux/module.h> +#include <linux/export.h> This commit is only changing the kernel dir; next targets will probably be mm, fs, the arch dirs, etc. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* rtmutex: tester: Remove the remaining BKL leftoversThomas Gleixner2011-02-221-3/+2
| | | | | | | We just leave the numbers assinged as commemoration and in case that someone was crazy enough to reimplement the test stuff out of tree. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* rtmutex-tester: Remove BKL testsArnd Bergmann2011-01-261-35/+4
| | | | | | | | | | | | | The BKL is going away, no need to test it any more. I left the definitions of the test case numbers in, so that the other tests do not get renumbered.

* rtmutex-tester: make it build without BKLArnd Bergmann2010-10-191-0/+6
| | | | | | | | | | | | | The big kernel lock is going away, so make sure that if it is disabled by Kconfig, we do not try to validate it, which would result in compile errors.

* sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-211-3/+4
| | | | | | | | | | | | | | | | | | | | | | This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Driver core: change sysdev classes to use dynamic kobject namesKay Sievers2008-01-241-1/+1
| | | | | | | | | | All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

| | | | | | | | | | | | | Move process freezing functions from include/linux/sched.h to freezer.h, so that modifications to the freezer or the kernel configuration don't require recompiling just about everything.

* [PATCH] Add try_to_freeze() to rt-test kthreadsLuca Tettamanti2006-07-141-0/+1
| | | | | | | | | | | | | | | When CONFIG_RT_MUTEX_TESTER is enabled kernel refuses to suspend the machine because it's unable to freeze the rt-test-* threads. Add try_to_freeze() after schedule() so that the threads will be freezed correctly; I've tested the patch and it lets the notebook suspends and resumes nicely.

* [PATCH] sched: cleanup, remove task_t, convert to struct task_structIngo Molnar2006-07-031-2/+2
| | | | | | | | | | | | cleanup: remove task_t and convert all the uses to struct task_struct. I introduced it for the scheduler anno and it was a mistake. Conversion was mostly scripted, the result was reviewed and all secondary whitespace and style impact (if any) was fixed up by hand.
