Mikulas Patocka 6930c0229f dm-snapshot: fix 'scheduling while atomic' on real-time kernels ... [ Upstream commit 8581b19eb2c5ccf06c195d3b5468c3c9d17a5020 ] There is reported 'scheduling while atomic' bug when using dm-snapshot on real-time kernels. The reason for the bug is that the hlist_bl code does preempt_disable() when taking the lock and the kernel attempts to take other spinlocks while holding the hlist_bl lock. Fix this by converting a hlist_bl spinlock into a regular spinlock.
