Subject: [PATCH 6/10] libata: add freeze/thaw to old EH LLDDs
Date: Wed, 04 Jul 2007 16:59:57 +0800 [thread overview]
Message-ID: <468B618D.6060003@tw.ibm.com> (raw)
In-Reply-To: <468B5C97.1000803@tw.ibm.com>
Patch 6/10:
Now that HSM polling code path uses freeze()/thaw() regardless of old EH or new EH.
Add freeze()/thaw() to old EH LLDDs for the HSM polling code.
