From 0a7ab79c5b5a16035e09b466c9013c8afc3b4bff Mon Sep 17 00:00:00 2001 From: Abhijith Das Date: Wed, 7 Jan 2009 16:03:37 -0600 Subject: GFS2: change gfs2_quota_scan into a shrinker Deallocation of gfs2_quota_data objects now happens on-demand through a shrinker instead of routinely deallocating through the quotad daemon.
