2012-02-29bug.h: add include of it to various implicit C usersPaul Gortmaker1-0/+1
With bug.h currently living right in linux/kernel.h there are files that use BUG_ON and friends but are not including the header explicitly. Fix them up so we can remove the presence in kernel.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-07-08plist: Remove the need to supply locks to plist headsDima Zavin1-6/+1
This was legacy code brought over from the RT tree and is no longer necessary.

2011-03-11plist: Add priority list testLai Jiangshan1-1/+80
Add test code for checking plist when the kernel is booting. Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> LKML-Reference: <4D107986.1010302@cn.fujitsu.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-03-11plist: Shrink struct plist_headLai Jiangshan1-19/+35
struct plist_head is used in struct task_struct as well as struct rtmutex. If we can make it smaller, it will also make these structures smaller as well. The field prio_list in struct plist_head is seldom used and we can get its information from the plist_nodes. Removing this field will decrease the size of plist_head by half.

2009-12-14plist: Make plist debugging raw_spinlock awareThomas Gleixner1-3/+5
plists are used with spinlocks and raw_spinlocks. Change the plist debugging to handle both types. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Peter Zijlstra <peterz@infradead.org> Acked-by: Ingo Molnar <mingo@elte.hu>
2008-07-26Use WARN() in lib/Arjan van de Ven1-6/+7
Use WARN() instead of a printk+WARN_ON() pair; this way the message becomes part of the warning section for better reporting/collection. In addition, one of the if() clauses collapes into the WARN() entirely now.
