If anyone has any objections, please let me know. ------------------ From: Alexander Aring commit ac5ee087d31ed93b6e45d2968a66828c6f621d8c upstream. This patch moves the msleep_interruptible() out of the non-sleepable context by moving the ls->ls_recover_spin spinlock around so msleep_interruptible() will be called in a sleepable context.
