I wish to print the call stacks of all the cpus. at a given time. How can i
do it?
for_each_cpu{
dump_stack() - Some function like this available? or i should write my own
code?
...
}
Any pointers would help.
Thank you,
Sandeep

Hi Sandeep,
This should be possible using ftrace without touching the code. I am not
sure how to trigger on a specific function but I think it should be
possible. Have a look at Documentation/trace/ftrace.txt

In the highmem.c file, the function kmap_high() does the following :

*Sorry for the previous incomplete mail*
In highmem.c, the function kmap_high() does the following :
BUG_ON(pkmap_count[PKMAP_NR(vaddr)] 2);
Why would this be a serious bug?
Don't usable entry have pkmap_count[] value as 0. (in map_new_virtual() )
if (!pkmap_count[last_pkmap_nr])
