Message-ID: <20140501231255.31890.67291.stgit@birch.djwong.org> Date: Thu, 01 May 2014 16:12:55 -0700 From: "Darrick J. Wong" <darrick.wong@...cle.com> To: tytso@....edu, darrick.wong@...cle.com Cc: linux-ext4@...r.kernel.org Subject: [PATCH 05/37] debugfs: teach logdump to deal with 64bit revoke tables The logdump command doesn't know how to deal with revoke tables in 64bit journals, so teach it to do this.
