Subject: [PATCH #upstream-fixes 1/2] libata: uninline atapi_cmd_type()
Date: Wed, 02 Apr 2008 17:28:46 +0900 [thread overview]
Message-ID: <47F343BE.4030103@gmail.com> (raw)
Uninline atapi_cmd_type(). It doesn't really have to be inline and
more case will be added which need to access unexported libata
variable.
