Btrfs: [PATCH] extent_map: fix locking for bio completion
The bio completion handlers can be run in any context, e.g. when using
the old ide driver they run in hardirq context with irqs disabled so
lockdep rightfully warns about using write_lock_irq useage in these
handlers.
This patch switches clear_extent_bit and set_extent_bit to
write_lock_irqsave to fix this problem.
