kernel: XFS data corruption using reflink

A flaw was found in the XFS filesystem. A race condition in the copy-on-write mechanism for reflinked files can cause writes to bypass the copy-on-write process and modify shared data blocks directly. As a result, data intended for a private copy may be written to the original shared location,...
