From 8f45c33decf62e1aaaa9411aae8fef6a38f95845 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Thu, 20 May 2010 16:00:36 +0200 Subject: [PATCH] ufs: Remove dead quota code UFS quota is non-functional at least since 2.6.12 because dq_op was set to NULL. Since the filesystem exists mainly to allow cooperation with Solaris and quota format isn't standard, just remove the dead code.
