Subject: [PATCH RESEND 07/11] s390/dasd: Remove %p format specifier from error messages
Date: Thu,  8 Feb 2024 17:42:46 +0100	[thread overview]
Message-ID: <20240208164248.540985-8-sth@linux.ibm.com> (raw)
In-Reply-To: <20240208164248.540985-1-sth@linux.ibm.com>

From: Jan Höppner <hoeppner@linux.ibm.com>

Printing pointer in error messages doesn't add any value since the
addresses are hashed. Remove the %p format specifier and adapt the error
messages slightly.

Replace %p with %px in ERP to get the actual addresses since ERP is used
for debugging purposes only anyway.
