            Bug ID: 218870
           Summary: F2FS mount/unmount results in invalid_blkaddr
           Product: File System
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: f2fs
          Assignee: filesystem_f2fs@kernel-bugs.kernel.org
          Reporter: patrik.plihal@gmail.com
        Regression: No

At least 3 people hit an issue with f2fs mount taking a long time (due to
fsck).

In 2 cases it's is the boot partition which delays boot time, in my case it
simply delays a mount.


I prepared a example to reproduce the invalid_blkaddr (and which I presume is
the root cause for the long-mount/fsck)

  1. dd if=/dev/zero of=test.img count=100 bs=1M
  2. mkfs.f2fs -f ./test.img
  3. fsck.f2fs test.img  | grep errors # nothing
  4. mount -t f2fs ./test.img ./mnt
  5. umount ./test.img
  6. fsck.f2fs test.img  | grep errors 
    # Info: fs errors: invalid_blkaddr
