Hello, Ive a user app and a device driver sharing memory via mmap. This block of memory contains info for a memory allocator. This is used by the user app to get memory or to decide to do another mmap. Now the kernel can basically return memory to the freelist, but doesnt want to be competing with the user app and corrupt the freelist. I obv dont want to make the kernel wait for the userapp(although i can guarantee that no deadlocks will ever occur). I would like to signal the process , the address within its process space that can be added to the freelist. Im a bit lost on the way to do this..Any pointers?
