X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=194074acacebc169ded90a4657193f5180015051;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git ext4: fix incorrect block reservation on quota transfer. 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.
