Hello Al,

I always base my patches on linux-next, which is usually correct,
and if it isn't, the maintainer usually says something :)

The patch in question is based on the latest linux-next tag:
next-20180316

It appears that the following three commits are in linux-next,
but not on your for-next branch @ your vfs git tree:
61fc3c8ce7f1 dcache: remove trailing whitespace
929387149a47 dcache: fix indirectly reclaimable memory accounting
ff335768ddd0 dcache: fix indirectly reclaimable memory accounting for CONFIG_SLOB

They appear to come from Andrew Morton's tree.

Would you prefer me to rebase my patch against your
for-next branch instead?

I'm using emacs, but having added show-trailing-whitespace
is my personal preference, however, I quite sure that I'm
not the only one who has an editor configured like this.


Kind regards,
Niklas
