Oggetto: ext4 filesystem corruption with 4.10-rc2 on ppc64le
Hi,
I'm consistently seeing ext4 filesystem corruption using a mainline
kernel. It doesn't take much to trigger it - download a ppc64le Ubuntu
cloud image, boot it in KVM and run:
sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot
And it never makes it back up, dying with rather severe filesystem
corruption.
I've narrowed it down to:
64e1c57fa474 ("ext4: Use clean_bdev_aliases() instead of iteration")
e64855c6cfaa ("fs: Add helper to clean bdev aliases under a bh and use it")
ce98321bf7d2 ("fs: Remove unmap_underlying_metadata")
Backing these patches out fixes the issue.
Anton
