I am strongly against making this the default. The change I've proposed, while interesting in a narrow case, is still an incomplete implementation of the architected VOP_FID/VFS_VGET protocol. Therefore, to limit the exposure of this behavior, I propose that it is only present when specifically requested, not by default. -- Bill Baker, 512-401-1081, x64081
