Subject: vmalloc.c question
Date: Fri, 19 Feb 1999 19:24:14 +0900 [thread overview]
Message-ID: <36CD3BCE.9D2AE90E@earthling.net> (raw)
I have a simple question about vmalloc.c. I'm probably missing something
obvious, but it appears to me that the list "vmlist" of the kernel's
virtual memory areas is not protected by any kind of locking mechanism,
and thus subject to races. (e.g. two CPUs trying to insert a new virtual
memory block in the same place at the same time in get_vm_area).
Or what am I missing?
Thanks,
Neil.
