Andreas Kling dd58d0f650 Kernel: Uncommit a shared COW page when discovering it was unshared ... When we hit a COW fault and discover than no other process is sharing the physical page, we simply remap it r/w and save ourselves the trouble. When this happens, we can also give back (uncommit) one of our shared committed COW pages, since we won't be needing it. We had this optimization before, but I mistakenly removed it in 50472fd69f since I had misunderstood it to be the reason for a panic.		2021-08-05 17:41:58 +02:00
