Hi Herbert,

Is the PCOMPRESS algorithm supposed to support asynchronous
implementations? In other words, are callers expected to handle the
-EINPROGRESS or -EAGAIN return codes that can be returned by an
asynchronous implementation?

Or is it assumed that if the CRYPTO_ALG_ASYNC flag is not set then the
code path must be synchronous?  If that's the case, should the pcompress
support be updated to look for synchronous implementations if the
CRYPTO_ALG_ASYNC flag isn't set or should asynchronous implementations
provide a synchronous fallback?

Thanks,
Tom
