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.
