- Make ObpReleaseCapturedName an actual function and rename it to ObpFreeObjectNameBuffer. Fix a bug in this function which was causing it to attempt freeing the UNICODE_STRING structure instead of the actual buffer.
- Implement ObpAllocateObjectNameBuffer instead of inlined code in ObpCaptureObjectAttributes. Enable usage of the Name Buffer Lookaside List since the bug in ObpFreeObjectNameBuffer has now been fixed. This should result in significant speedup and less fragmentation of pool memory.
- Allocate object names in the paged pool instead of non-paged pool, if we can't use the lookaside list.
