Issue of the Implementation # F0008

Brief

f2fs: BUG_ON() is triggered in recover_inode_page() when mount valid f2fs filesystem

Detailed Description

When mount given f2fs filesystem image, kernel BUG arise.

fsck.f2fs reports that given filesystem is valid.

Reproducing

With device <dev> initially containing given f2fs image, next steps will trigger BUG_ON:

mount -t f2fs <dev> <mount-point>

or

mkfs -t f2fs <dev>
mount -t f2fs -omand <dev> <mount-point>
touch <mount-point>/file.txt
setfacl <mount-point>/file.txt
umount <mount-point>
mount -t f2fs <dev> <mount-point>
