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

Hi Stephen... is there something I should do differently? I might be
using an older
version of the patch, it was sent to me around three weeks ago.

>>Caused by commit
 >> 50fb0a7f43c0 ("orangefs: Move s_kmod_keyword_mask_map to
orangefs-debugfs.c")
>>merging badly with commit
 >> 063f8013373a ("orangefs: move s_kmod_keyword_mask_map[] into debugfs.c")

One has "Move" the one I'm using has "move", as if the author (Arnd)
made an update
to the patch and maybe I missed it...?
