Re: Fwd: ext4 extents.c bug

[Frej Eriksson]

Hi,

Thank you for your the information! If i get you correct does it mean
that you need to have an updated version of both the kernel and
e2fsprogs in order to have the issue fixed? Or is it enough to run
e2fsprogs with the patch applied?

Best regards,
Frej Eriksson
