Syzbot has reported the following KMSAN splat:
BUG: KMSAN: uninit-value in f2fs_new_node_page+0x1494/0x1630
f2fs_new_node_page+0x1494/0x1630
f2fs_new_inode_page+0xb9/0x100
f2fs_init_inode_metadata+0x176/0x1e90
f2fs_add_inline_entry+0x723/0xc90
f2fs_do_add_link+0x48f/0xa70
f2fs_symlink+0x6af/0xfc0
vfs_symlink+0x1f1/0x470
do_symlinkat+0x471/0xbc0
__x64_sys_symlink+0xcf/0x140
x64_sys_call+0x2fcc/0x3d90
do_syscall_64+0xd9/0x1b0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
Local variable new_ni created at:
f2fs_new_node_page+0x9d/0x1630
f2fs_new_inode_page+0xb9/0x100
So adjust 'f2fs_get_node_info()' to ensure that 'flag'
field of 'struct node_info' is always initialized.
