[dm-devel] Path check interval in multipathd is 1 second longer

[Kiyoshi Ueda <k-ueda ct jp nec com>]

Hi Christophe,

Current path check interval is 1 second longer than polling_interval
setting in multipath.conf.

This bug affects the "no_path_retry" option.
For example, if no_path_retry is set in 1, retry (== path check) will
not be launched in no-path situation.
