Subject: [PATCH 1/4] mpt2sas: unique ioctl magic number
Date: Thu, 9 Apr 2009 03:40:25 -0600 [thread overview]
Message-ID: <20090409094023.GA7063@lsil.com> (raw)
The current magic number is shared with mptsas driver. This to be unique to
fix issues with register_ioctls32_conversion in older kernels. We are making
this change across all versions of the sas2.0 drivers.
