[dm-devel] [PATCH v2 0/6] dm: support IO polling for bio-based dm device

2021-01-26 Thread Jeffle Xu
Since currently we have no simple but efficient way to implement the bio-based IO polling in the split-bio tracking style, this patch set turns to the original implementation mechanism that iterates and polls all underlying hw queues in polling mode. One optimization is introduced to mitigate the
