From 13f5fa1a8864818c97a8db205d80351d3ce38e3f Mon Sep 17 00:00:00 2001 From: Joseph Gmitter Date: Wed, 7 Dec 2016 11:19:50 -0500 Subject: [PATCH] LUDOC-292 fix: Update formatting error in file path At some point the following line was changed in the Visualizing Results section of the benchmarking section of the manual: /proc/fs/lustre/obdfilter/*/brw_stats was accidentally changed to: /proc/fs/lustre/obdfilter/ Also, "*/brw_stats" appeared in a tag, which was not the intent. The patch also updates these 3 paragraph for 80 character max per line.
