[dm-devel] [PATCH] Avoid that reloading a map sporadically triggers I/O errors

[Bart Van Assche]

Avoid that reloading a map while there are no paths triggers a flush
and hence unwanted I/O errors if 'queue_if_no_path' is enabled.

Fixes: commit d569988e7528 ("libmultipath: Fixup 'DM_DEVICE_RELOAD' handling")
