Date: Mon, 24 Jun 2013 13:18:06 +0530 From: Aruna Balakrishnaiah <aruna@...ux.vnet.ibm.com> To: ccross@...roid.com, tony.luck@...el.com, linux-kernel@...r.kernel.org, keescook@...omium.org, cbouatmailru@...il.com Cc: jkenisto@...ux.vnet.ibm.com, benh@...nel.crashing.org, ananth@...ibm.com, mahesh@...ux.vnet.ibm.com Subject: [PATCH] pstore: Fail to unlink if a driver has not defined pstore_erase pstore_erase is used to erase the record from the persistent store. So if a driver has not defined pstore_erase callback return -EINVAL instead of unlinking a file as deleting the file without erasing its record in persistent store will give a wrong impression to customers.
