From 49528b4e479195e5db4fe51fcd5ddd97901efc16 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 6 Jan 2012 16:48:50 -0500 Subject: GFS2: Fix a use-after-free that coverity spotted In function gfs2_inplace_release it was trying to unlock a gfs2_holder structure associated with a reservation, after said reservation was freed. The problem is that the statements have the wrong order. This patch corrects the order so that the reservation is freed after the gfs2_holder is unlocked.
