From 2aba1b5b4f78d56a764b92bae58298ad3fffdc4a Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Tue, 19 May 2015 09:11:23 -0500 Subject: [PATCH] GFS2: Reintroduce a timeout in function gfs2_gl_hash_clear At some point in the past, we used to have a timeout when GFS2 was unmounting, trying to clear out its glocks. If the timeout expires, it would dump the remaining glocks to the kernel messages so that developers can debug the problem. That timeout was eliminated, probably by accident. This patch reintroduces it.
