Subject: [PATCH 4/5] mvsas: remove mvs_slave_{alloc|configure}
Date: Tue, 20 Sep 2011 15:10:55 -0700	[thread overview]
Message-ID: <20110920221051.1094.39578.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20110920220819.1094.12265.stgit@localhost6.localdomain6>

libsas now handles:
1/ limiting ata scanning to lun0
2/ maximizing the queue_depth of sas devices (up to 256, mvsas only
   supports 64)
3/ changes to /sys/block/<sdX>/device/queue_depth for ata devices
