Isn't the problem with GPFS_DENY_DELETE that it is mapped to a
combination of other flags internally? The last time we discussed this
GPFS_DENY_DELETE was not an independent bit in GPFS. This goes along
with Ralph's question about the precise semantics. Can we get someone
from the GPFS team to describe exactly what's going on internally?

Thanks, Volker
