[PATCH 4/9] libmultipath: Set the scsi timeout parameters by path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of dev_loss, fast_io_fail, and eh_deadline belonging to the
multipath structure, have them belong to the path structure. This means
that they are selected per path, and that sysfs_set_scsi_tmo() doesn't
assume that all paths of a multipath device will have the same value.
Currently they will all be the same, but a future patch will make it
possible for paths to have different values based on their protocol.
