Subject: [PATCH v1 02/19] xfsprog: Replace attribute parameters with struct xfs_name
Date: Fri, 9 Aug 2019 14:37:47 -0700 [thread overview]
Message-ID: <20190809213804.32628-3-allison.henderson@oracle.com> (raw)
In-Reply-To: <20190809213804.32628-1-allison.henderson@oracle.com>
This patch replaces the attribute name, length and flags parameters with a
single struct xfs_name parameter. This helps to clean up the numbers of
parameters being passed around and pre-simplifies the code some.
