[PATCH -next v4 1/5] block, bfq: remove set but not used variable in __bfq_entity_update_weight_prio
Posted by Yu Kuai 3 years, 5 months ago
From: Yu Kuai <yukuai3@huawei.com>

After the patch "block, bfq: cleanup bfq_weights_tree add/remove apis"),
the local variable 'bfqd' is not used anymore, thus remove it.

Thanks for helping out. I'm not sure which commit id to use since the
fixed patch is not in linux-next yet, does the commit id stay the same
when the patch applied from for-6.2 to next ?

Thanks,

linux-next shas are not stable, but since you're sending this to the
linux-block list and against the block tree, that's obviously where
you'd find that commit.
