## Description

In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to clear dirty inode in f2fs_evict_inode()  As Yanming reported in bugzilla:  https://bugzilla.kernel.org/show_bug.cgi?id=215904  The kernel message is shown below:  kernel BUG at fs/f2fs/inode.c:825! Call Trace:  evict+0x282/0x4e0  __dentry_kill+0x2b2/0x4d0  shrink_dentry_list+0x17c/0x4f0  shrink_dcache_parent+0x143/0x1e0  do_one_tree+0x9/0x30  shrink_dcache_for_umount+0x51/0x120  generic_shutdown_super+0x5c/0x3a0  kill_block_super+0x90/0xd0  kill_f2fs_super+0x225/0x310  deactivate_locked_super+0x78/0xc0  cleanup_mnt+0x2b7/0x480  task_work_run+0xc8/0x150  exit_to_user_mode_prepare+0x14a/0x150  syscall_exit_to_user_mode+0x1d/0x40  do_syscall_64+0x48/0x90  The root cause is: inode node and dnode node share the same nid, so during f2fs_evict_inode(), dnode node truncation will invalidate its NAT entry, so when truncating inode node, it fails due to invalid NAT entry, result in inode is still marked as dirty, fix this issue by clearing dirty for inode and setting SBI_NEED_FSCK flag in filesystem.  output from dump.f2fs: [print_node_info: 354] Node ID [0xf:15] is inode i_nid[0]                      		[0x       f : 15]
