From 388667bed591b2359713bb17d5de0cf56e961447 Mon Sep 17 00:00:00 2001 From: Arthur Jones Date: Fri, 25 Jul 2008 12:03:38 -0700 Subject: [PATCH] md: raid10: wake up frozen array When rescheduling a bio in raid10, we wake up the md thread, but if the array is frozen, this will have no effect. This causes the array to remain frozen for eternity. We add a wake_up to allow the array to de-freeze. This code is nearly identical to the raid1 code, which has this fix already.
