From 641bb3246dbb64c0b4a0b6dfa6a024e82c155533 Mon Sep 17 00:00:00 2001 From: Martin Brandenburg Date: Mon, 28 Mar 2016 17:18:27 -0400 Subject: [PATCH] orangefs: don't put readdir slot twice This was quite an oversight. After a readdir, the module could not be unloaded, the number of slots is wrong, and memory near the slot bitmap is possibly corrupt. Oops.
