Subject: Re: linux-next: build failure after merge of the vfs tree

Hi all...

I'm having a chicken-and-egg moment here...

I think "posix acls: Remove duplicate xattr name definitions" got into
linux-next after
Linus committed  Linux 4.4-rc4.

Unless I merge my for-next with Linus' tree at the current (arbitrary)
point, I need to wait
until I can merge with rc5 before I can apply this fix.

I know Linus hates to get pull requests for stuff that's not based on
a discrete tag,
I'm not sure what's appropriate for linux-next... ?

-Mike
