Hi Amir,

thanks for the review.

This gave me a good chuckle. :)  I will check for a
EXT4_ERR_EFSCORRUPTED and propose a fix on ext4.

As requested, I will not send a new version of the test for now. I
published them on the following unstable branch:

  https://gitlab.collabora.com/krisman/ltp -b fan-fs-error

The v1, as submitted in this thread is also available at:

  https://gitlab.collabora.com/krisman/ltp -b fan-fs-error-v1

Thanks,
