[PATCH] select_parent

[Mark Hemment]

  Minor patch.

  fs/dcache.c:select_parent() moves unused dentries to the head of the
unused list, ready for a call to prune_dcache().  However, it doesn't
clear the referenced-bit.  At worst, this could result in a bit of
extra work and a few unnecessary dentires reaped.

  Please apply.
