From 749586b7d34df910118bff2c248d08877d772e81 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 20 Nov 2012 14:11:15 +1100 Subject: [PATCH] md/raid5: use async_tx_quiesce() instead of open-coding it. handle_stripe_expansion contains: if (tx) { async_tx_ack(tx); dma_wait_for_async_tx(tx); } which is very similar to the body of async_tx_quiesce(), except that the later handles an error from dma_wait_for_async_tx() (admittedly by panicing, but that decision belongs in the dma code, not the md code). So just us async_tx_quiesce().
