From: Anna-Maria Gleixner Date: Fri, 4 May 2018 17:45:33 +0200 Subject: [PATCH 3/3] drivers/md/raid5: Do not disable irq on release_inactive_stripe_list() call Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.18/older/patches-4.18.5-rt3.tar.xz There is no need to invoke release_inactive_stripe_list() with interrupts disabled. All call sites, except raid5_release_stripe(), unlock ->device_lock and enable interrupts before invoking the function. Make it consistent.
