Please look at the following scenario:

Hi,
Regarding your question about the previous thread:
Think of a context switch, let's say between a userspace process and a
kernel thread. A context switch is done between two processes
(processes are represented by struct task_struct). So when you look at
context_switch() prototype, you see:

Hi,
Once upon a time there was a feature removal schedule in Documentation:
http://lxr.free-electrons.com/source/Documentation/feature-removal-schedule.txt?v=3.6
Was it removed ? I cannot find it in recent kernels (like 3.9.0-rc4)

Hi,
In init_clocksource_sysfs() method,
device_register() adds the folder:
/sys/devices/system/clocksource/clocksource0,
whereas subsys_system_register() adds the parent folder
(/sys/devices/system/clocksource)

Just curious, is there a cap on how much data can be in writeback at
the same time?
I'm asking because I have over a gigabyte of data in dirty, but
during flush, only about 60k or so is in writeback at any one time.
Is there a cap of sorts, and if so, how do I remove it?

There's a lot of tunables in /proc/sys/vm - everything from drop_caches
to swappiness to vfs_cache_pressure. Note that they all interact in mystical
