> The encryption zone APIs should be optimized to extensively use IIPs to eliminate path
resolutions.  The performance penalties incurred by common operations like creation of file
statuses may be reduced by more extensive short-circuiting of EZ lookups when no EZs exist.
 All file creates should not be subjected to the multi-stage locking performance penalty required
only for EDEK generation.
