Hi All,
I was referring to Unreliable Guide To Locking by Paul Rusty Russell.
Here is a quote below :-
If a bottom half shares data with user context, you have two problems.
Firstly, the current user context can be interrupted by a bottom half, and
secondly, the critical region could be
Hi All,
I am working on a ARM based custom platform which has a mmc controller
(by Designware.) The mmc controller driver is dw-mmc.c.
On kernel bootup, I insert the driver and then I mount the mmc device
on /mnt. I am able to perform file-system operation(ls, cp, mv, rm) on
/mnt. Then without
Thank you very much for replying.
I actually notice that there are many static functions in that file. However,
some of them show up in symbol table, the rest do not. So what you are saying
is that there is no connection between being a static function and showing up
in kernel symbol table.

mode or back to normal mode from inside the kernel*. I looked a bit over the
Internet to find a recent example of USB Device Drivers but

Hi, dear list,
I want to be clear about the USB hotplug procedure.
I read Linux Device Driver and Documentation/usb/hotplug.txt, and
google much. Per my understanding, the USB hotplug works as following:
1) Insertion of physical U-disk will trigger a hardware interrupt. And
interrupt handler
I think I found the cause. After GCC optimization, those static
functions are not visible any more in the object file (not sure
because of function inlining?). Thus, they don't show up in vmlinux or
/proc/kallsyms.
I tried changing it to -O0, they all show up.
Thanks,
Ji
