Subject: [PATCH] common/dmthin: Fix grep command for finding exact value
Date: Thu, 16 Mar 2017 10:18:50 +0530	[thread overview]
Message-ID: <1489639730-15004-1-git-send-email-harish@linux.vnet.ibm.com> (raw)

Sometimes there are multiple occurences of pool_name and data_name in
dmsetup command which causes failures while adding in next line.
This patch greps for pool_name at start of line.
