This patch series makes the ib_srp driver better suited for use in a H.A. setup because: - Switchover without triggering read or write errors become possible. Such errors are bad because these can make a filesystem switch to read-only mode. - A ping mechanism has been added that allows to reduce the switch-over time. - Disconnecting from a target without unloading ib_srp becomes possible. - Switchover can be triggered explicitly by deleting an initiator device. Changes since v1: - Switched from iSCSI-style sysfs parameters to FC-style sysfs parameters (fast_io_fail_tmo and dev_loss_tmo). - Restored the original behavior of "add_target": a second login to a target is again allowed and also stops error recovery for previously created sessions. - Changed srp_disconnect_target() such that it waits for the last completion after a disconnect. - Moved code for enlarging block layer timeout from srp_slave_alloc() to srp_slave_configure(), and moved that function to after srp_reset_host(). Also addressed Dave's other comments to the code for enlarging the timeout value. - Split the "ib_srp: Rework error handling" patch in three separate patches to make reviewing easier. - Added a patch that slightly improves ib_srp performance. - Made comment more detailed of patch 09/14 "srp_transport: Fix attribute registration" - Merged multiline log strings into a single line. - Dropped patch 05/14 "ib_srp: Avoid that late SRP replies cause trouble". - Implemented several other small changes.
