CVE-2024-27080

CVE-2024-27080 resolves a race in the Linux kernel's btrfs fiemap handling. The change stops locking the entire fiemap target range to avoid a deadlock with memory-mapped buffers, but creates a race where delalloc ranges in holes can be missed. As a result, fiemap consumers may not see delalloc d...
