6.6-stable review patch. If anyone has any objections, please let me know.

From: Alexander Aring aahringo@redhat.com
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.
