Summary: This article discusses a kernel optimization and fix issue related to the Xarray data structure in the Linux kernel. The issue was first noticed as a potential problem in a commit submitted to the Linux community in April 2023, but it was not until September 2023 that it was officially highlighted. The problem was that a certain race condition in the Xarray code could lead to data corruption, but due to the low reproduction probability and lack of effective debug information, it was difficult for the community to determine the root cause.
