softirq: No local_irq_save() in local_bh_enable()

[ratheesh kannoth]

Hi list,

Below was quoted from
http://linux-kernel.2935.n7.nabble.com/PATCH-softirq-Use-local-irq-save-in-local-bh-enable-td383387.html

"Anyway, a commit 0f476b6d91a1395bda6464e653ce66ea9bea7167 "softirq:
remove irqs_disabled warning from local_bh_enable" can break things
after changing from local_irq_save() to local_irq_disable(). Before
this commit there was only a warning, now a lockup is possible, so
it could be treated as a regression. This patch reverts the change
in irqs. "


But i could not see the usage  of local_irq_save() in newer kernels (
3.7.3 ). Could you please tell me , why we did not take this patch ?
