Subject: Re: [PATCH 02/12 v2] Revert "ext4: fix fsx truncate failure"

Hi Lukas,

This patch set has changes to the VFS, XFS, and ext4, and there are
cross dependencies between them.  Is there any way you can disentagle
the dependencies between the patches so we don't need to worry about
how these get pulled in during the merge window?

I suppose could try to get the XFS folks to sign off with my carrying
this patch in the ext4 tree, since the bulk of the changes are
ext4-related, but it is a bit of a complication.

Hi Ted,

there is no VFS change, MM is probably what you've had in mind ? So
the only reason why there are xfs, mm and tmpfs changes is that I am
changing truncate_partial_page() and a small side effect is changed
calling conventions.

We can push patches 3, 4, 5 and 6 through the mm tree. But we'll
have to make sure that it will land before ext4 changes since I am
using the new truncate_partial_page() behaviour in ext4. Will that
be possible ?

Hugh ?
