The iSCSI session recovery_tmo setting is writeable in sysfs, but it's also set every time a connection is established when parameters are set from iscsid over netlink. That results in the timeout being reset to the default value after every recovery. The DM multipath tools want to use the sysfs interface to lower the default timeout when there are multiple paths to fail over. It has caused confusion that we have a writeable sysfs value that seem to keep resetting itself. This patch adds an in-kernel flag that gets set once a sysfs write occurs, and then ignores netlink parameter setting once it's been modified via the sysfs interface. My thinking here is that the sysfs interface is much simpler for external tools to influence the session timeout, but if we're going to allow it to be modified directly we should ensure that setting is maintained.
