From 4f37bc04805e20f2a8907a49f06b310e4ebf82b8 Mon Sep 17 00:00:00 2001 From: "John L. Hammond" Date: Tue, 23 Jul 2013 00:06:24 +0800 Subject: [PATCH] staging/lustre/llite: use READ, WRITE around ll_rw_stats_tally() In vvp_io_write_start() the stats function ll_rw_stats_tally() was incorrectly called with a rw argument of 0. Correct this and use the macros READ and WRITE in and around ll_rw_stats_tally() for clarity.
