What to do
AI-suggested
A patch has been applied to the Linux kernel to fix this issue by shrinking read extent nodes in batches. Users should update to the fixed kernel version once available. Since no specific fixed versions or patch links are provided, check the official Linux kernel advisories or repositories for the relevant patch.
Description
A vulnerability in the Linux kernel's f2fs filesystem code could cause a kernel hang due to prolonged holding of a read-write lock when shrinking a large extent tree. The issue arises because the shrink operation holds the rwlock for an extended period if the extent tree contains many nodes. A patch has been applied to shrink the read extent nodes in batches, reducing the time the lock is held and preventing the hang.
