removed the option to specify 'pathname' as NULL, since
this was redundant with AT_EMPTY_PATH + pathname == "".

Michael Kerrisk a18cc179a7 ioctl_userfaultfd.2: Drop some unneeded text 
From a conversation with Mike Rapoport:

What does "consistent" mean?
    Actually, I though I've copied this text from Andrea's docs,
    but now I've found out it was my wording and I really don't
    remember now what was my intention for "consistent" :) My
    guess is that I was thinking about atomicity of UFFDIO_COPY,
    or the fact that from the faulting thread perspective the
    page fault handling is the same whether it's done in kernel
    or via userfaultfd...  That said, maybe it'd be better just
    to drop "in a consistent way".
