Message-Id: <1443672762-982936-30-git-send-email-green@linuxhacker.ru> Date: Thu, 1 Oct 2015 00:12:39 -0400 From: green@...uxhacker.ru To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, devel@...verdev.osuosl.org, Andreas Dilger <andreas.dilger@...el.com> Cc: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Lustre Development List <lustre-devel@...ts.lustre.org>, Oleg Drokin <green@...uxhacker.ru> Subject: [PATCH 29/32] staging/lustre/ldlm: Remove unused exported symbols. From: Oleg Drokin <green@...uxhacker.ru> This rather large patch prunes all unused EXPORT_SYMBOLS and marks functions only used locally as static lustre ldlm module. The only two remaining nonstatic functions that should be static now are: ldlm_cancel_lru_local ldlm_resource_putref_locked But some bigger code shuffling around is needed to achieve that, so it's left for a future patch.
