It appears unhelpful to me for flush_command_buffer() to block all progress elsewhere for the given IOMMU by holding its lock while waiting for command completion. There's no real need for callers of that function or of send_iommu_command() to hold the lock. Contain all command sending related locking to the latter function.Signed-off-by: Jan Beulich <jbeul...@suse.com>
