Subject: [PATCH] remove CONFIG_LBD ifdefs from fusion
Date: Mon, 31 May 2004 13:53:48 +0200 [thread overview]
Message-ID: <20040531115348.GB16143@lst.de> (raw)
The CONFIG_LBD case is also fine for !CONFIG_LBD, just a bit more
complicated in the source (but the compile optimizes that away -
->bios_param isn't exactly a fast-path either..)
