Subject: [PATCH v14 08/15] xfs: Handle krealloc errors in xlog_recover_add_to_cont_trans
Date: Fri, 18 Dec 2020 00:29:10 -0700 [thread overview]
Message-ID: <20201218072917.16805-9-allison.henderson@oracle.com> (raw)
In-Reply-To: <20201218072917.16805-1-allison.henderson@oracle.com>
Because xattrs can be over a page in size, we need to handle possible
krealloc errors to avoid warnings
