[PATCH 0/4] s390/dasd: fixes for RCD retry and BIODASDCHECKFMT

[Stefan Haberland <sth@linux.ibm.com>]

Hi Jens,

please apply the following DASD fixes.

 - Re-initialize the RCD buffer magic "V1.0" before every start of the
   request to fix a condition where z/VM omitted the UIT and the paths
   were wrongly reported as leading to different devices.
 - Two fixes for the BIODASDCHECKFMT ioctl, both reported by Sashiko:
   a wrong free plus a refcount leak in the dasd_eckd_build_check_tcw()
   error path, and an info leak caused by trusting the userspace-supplied
   result field.
 - A typo fix in a function name, dasd_sleep_on_immediatly(). It is a
   prerequisite for the RCD patch.


Thanks,
Stefan
