In the Linux kernel, the following vulnerability has been resolved:

f2fs: ensure node page reads complete before f2fs_put_super() finishes

Xfstests generic/335, generic/336 sometimes crash with the following message:

F2FS-fs (dm-0): detect filesystem reference count leak during umount, type: 9, count: 1 ------------[ cut here ]------------ kernel BUG at fs/f2fs/super.c:1939! Oops: invalid opcode: 0000 [#1] SMP NOPTI CPU: 1 UID: 0 PID: 609351 Comm: umount Tainted: G W 6.17.0-rc5-xfstests-g9dd1835ecda5 #1 PREEMPT(none) Tainted: [W]=WARN Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:f2fs_put_super+0x3b3/0x3c0 Call Trace: generic_shutdown_super+0x7e/0x190 kill_block_super+0x1a/0x40 kill_f2fs_super+0x9d/0x190 deactivate_locked_super+0x30/0xb0 cleanup_mnt+0xba/0x150 task_work_run+0x5c/0xa0 exit_to_user_mode_loop+0xb7/0xc0 do_syscall_64+0x1ae/0x1c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e ---[ end trace 0000000000000000 ]---

It appears that sometimes it is possible that f2fs_put_super() is called before all node page reads are completed. Adding a call to f2fs_wait_on_all_pages() for F2FS_RD_NODE fixes the problem.
