Subject: Asynchronous usage of PCOMPRESS
Date: Mon, 10 Nov 2014 12:16:51 -0600	[thread overview]
Message-ID: <54610113.3040200@amd.com> (raw)

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
