From 36350462814739e1f38cba59a6900ebadb08d3bb Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 19 May 2010 16:28:56 +0200 Subject: udf: Remove dead quota code Quota on UDF is non-functional at least since 2.6.16 (I'm too lazy to do more archeology) because it does not provide .quota_write and .quota_read functions and thus quotaon(8) just returns EINVAL. Since nobody complained for all those years and quota support is not even in UDF standard just nuke it.
