Great... OK, saner splitup of that sucker (equivalent to combination of these two patches) is in vfs.git#for-linus.
Review and testing would be very welcome.
PS: The diff between that and aforementioned "both patches applied" is noise - dentry and parent declarations had been moved into the loop body there, while in #for-linus they are left alone. So Mika's testing results should apply to that one as well.
