Title
f2fs: fix infinite loop in __insert_extent_tree()
Summary
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix infinite loop in __insert_extent_tree() When we get wrong extent info data, and look up extent_node in rb tree, it will cause infinite loop (CONFIG_F2FS_CHECK_FS=n). Avoiding this by return NULL and print some kernel messages in that case.
