From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Simmons Date: Mon, 16 Apr 2018 00:10:00 -0400 Subject: [lustre-devel] [PATCH 18/25] staging: lustre: libcfs: clear up failure patch in cfs_cpt_*_print In-Reply-To: <1523851807-16573-1-git-send-email-jsimmons@infradead.org> References: <1523851807-16573-1-git-send-email-jsimmons@infradead.org> Message-ID: <1523851807-16573-19-git-send-email-jsimmons@infradead.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Greg Kroah-Hartman , devel@driverdev.osuosl.org, Andreas Dilger , Oleg Drokin , NeilBrown Cc: Dmitry Eremin , Linux Kernel Mailing List , Lustre Development List From: Dmitry Eremin Currently both cfs_cpt_table_print() and cfs_cpt_distance_print() handle the error path in a confusing way. Simplify it so it just returns E2BIG on failure instead of testing rc value before exiting.
