You can\nreproduce the bug by running the following commands:\n\nThe kernel message is shown below:\n\nkernel BUG at fs/f2fs/f2fs.h:2511!\nCall Trace:\n f2fs_remove_inode_page+0x2a2/0x830\n f2fs_evict_inode+0x9b7/0x1510\n evict+0x282/0x4e0\n do_unlinkat+0x33a/0x540\n __x64_sys_unlinkat+0x8e/0xd0\n do_syscall_64+0x3b/0x90\n entry_SYSCALL_64_after_hwframe+0x44/0xae\n\nThe root cause is: .total_valid_block_count or .total_valid_node_count\ncould fuzzed to zero, then once dec_valid_node_count() was called, it\nwill cause BUG_ON(), this patch fixes to print warning info and set\nSBI_NEED_FSCK into CP instead of panic.",
