sysfs: simplify handling for s_active refcount
NeilBrown <neilb(a)> writes: s_active counts the number of active references to a 'sysfs_direct'. When we wish to deactivate a sysfs_direct, we subtract a large number for the refcount so it will always appear negative. When it is negative, new references will not be taken. After that subtraction... 29 Mar 2010 04:45
sysfs: make s_count a kref
NeilBrown <neilb(a)> writes: s_count in sysfs behaves exactly like a kref, so change it to be one. This requires adding a KREF_INIT macro to kref.h Except where it doesn't. The whole no_recurse thing is definitely not idiomatic kref usage. I could find only 3 instances of someone even looking at ... 26 Mar 2010 01:25

cputimers/proc: do_task_stat()->task_times() can race with getrusage()
* Oleg Nesterov <oleg(a)> [2010-03-24 21:45:50]: do_task_stat()->task_times() can race with getrusage(), they both can try to update task->prev_Xtime at the same time.

[PATCH] lockdep: Make lockstats counting per cpu
Locking statistics are implemented using global atomic variables. This is usually fine unless some path write them very often. This is the case for the function and function graph tracers that disable irqs for each entry saved (except if the function tracer is in preempt disabled only mode). And calls to local_i... 25 Mar 2010 23:11
