Bug#389618: ktimemon incorrectly reports slab usage

[James Stark <starkj@uoguelph.ca>]

Package: kdeaddons
Version: 3.5.4-1
Tags: patch, upstream
Forwarded: 134704@bugs.kde.org

ktimemon is reporting memory used by the slab twice.  Once as kernel memory and 
once as user memory.  For small slab sizes the effect of this is not noticeable, 
however once the slab is allowed to grow (running updatedb will do this) it will 
have the effect of making all of the memory appear to be consumed.  A simple 
inspection of /proc/meminfo will show that ktimemon is reporting an incorrect 
usage.  This can be alarming to the user.

I have attached a patch that corrects the problem, by subtracting the kernel 
memory usage reported by ktimemon (this seems to only be the slab) from the user 
memory usage.

I have also taken the liberty of filing a report in the kde bug tracking system 
for this issue as well.  The URL is:  http://bugs.kde.org/show_bug.cgi?id=134704
