Subject: [PATCH 4/4] ext4: fix incorrect block reservation on quota transfer.
Date: Wed, 25 Nov 2009 09:57:41 +0300	[thread overview]
Message-ID: <1259132261-16785-4-git-send-email-dmonakhov@openvz.org> (raw)
In-Reply-To: <1259132261-16785-3-git-send-email-dmonakhov@openvz.org>

Inside ->setattr() call both ATTR_UID and ATTR_GID may be valid
This means that we may end-up with transferring all quotas. Add
we have to reserve QUOTA_DEL_BLOCKS for all quotas, as we do in
case of QUOTA_INIT_BLOCKS.
