SRP_RECONNECT_RPORT(9)                    SCSI mid layer                   SRP_RECONNECT_RPORT(9)



NAME
       srp_reconnect_rport - reconnect to an SRP target port

SYNOPSIS
       int srp_reconnect_rport(struct srp_rport * rport);

ARGUMENTS
       rport
           SRP target port.

DESCRIPTION
       Blocks SCSI command queueing before invoking reconnect such that queuecommand won't be
       invoked concurrently with reconnect from outside the SCSI EH. This is important since a
       reconnect implementation may reallocate resources needed by queuecommand.

NOTES
       - This function neither waits until outstanding requests have finished nor tries to abort
       these. It is the responsibility of the reconnect function to finish outstanding commands
       before reconnecting to the target port. - It is the responsibility of the caller to ensure
       that the resources reallocated by the reconnect function won't be used while this function
       is in progress. One possible strategy is to invoke this function from the context of the
       SCSI EH thread only. Another possible strategy is to lock the rport mutex inside each SCSI
       LLD callback that can be invoked by the SCSI EH (the scsi_host_template.eh_*() functions
       and also the scsi_host_template.queuecommand function).
