From 2602b740e45cc64feb55d5a9ee8db744ab3becbb Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 13 Mar 2017 14:36:32 +0200 Subject: [PATCH] mmc: block: Fix is_waiting_last_req set incorrectly Commit 15520111500c ("mmc: core: Further fix thread wake-up") allowed a queue to release the host with is_waiting_last_req set to true. A queue waiting to claim the host will not reset it, which can result in the queue getting stuck in a loop.
