Subject: [PATCH v2 08/27] xfsprogs: Remove all strlen calls in all xfs_attr_* functions for attr names
Date: Sat, 9 Jun 2018 22:07:33 -0700 [thread overview]
Message-ID: <1528607272-11122-9-git-send-email-allison.henderson@oracle.com> (raw)
In-Reply-To: <1528607272-11122-1-git-send-email-allison.henderson@oracle.com>
Parent pointer attributes use a binary name, so strlen will not work.
Calling functions will need to pass in the name length
