Subject: [Bisected] commit 71574865 (vfs: do_last(): common slow lookup)
 breaks CUPS printing

Printing with CUPS is broken on the current git tree. Whenever I print a page
the job just sits in the CUPS queue showing "processing". But it never reaches
the printer.  (My CUPS version is 1.5.2. Filesystem is xfs.)

I've bisected this issue to:

commit 7157486541bffc0dfec912e21ae639b029dae3d3

    vfs: do_last(): common slow lookup
    
    Make the slow lookup part of O_CREAT and non-O_CREAT opens common.
    
    This allows atomic_open to be hooked into the slow lookup part.
