From 74f783af95c982aef6d3a1415275650dcf511666 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 19 Aug 2008 14:51:22 +0200 Subject: quota: Add callbacks for allocating and destroying dquot structures Some filesystems would like to keep private information together with each dquot. Add callbacks alloc_dquot and destroy_dquot allowing filesystem to allocate larger dquots from their private slab in a similar fashion we currently allocate inodes.
