Hello.

I have been seeing usage of mmap() with MAP_FIXED flag in __bl_uncommit 
which is used when M_DOTRIMMING is defined . What this flag is supposed 
to provide?
Can anybody tell me why usage of mmap() is needed in this case, since we 
already have mapping of this area?

Thanks in advance.
Michael.
