I have a rudimentary question as I'm new to the Linux kernel. Is there a
resource that can be acquired shared so that multiple threads can read data
from a protected region and not block each other? It seems that the
semaphore in the Linux kernel is only exclusively acquirable. I need to be
able to share read access from several threads to some global structures and
don't want them to block.
I do want blocking whenever I have to modify the structures though. Thus I'm
looking for a way to perform synchronization for reads (shared) and writes
(exclusively) in the kernel. I assume it can be done it's just that I'm not
sure how to do it yet. This is probably a very easy question.
Thanks in advance.
