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 ?
