The current strategy in ib_srp for posting receive buffers is: * Post one buffer after channel establishment. * Post one buffer before sending an SRP_CMD or SRP_TSK_MGMT to the target. As a result, only the first non-SRP_RSP information unit from the target will be processed. If that first information unit is an SRP_T_LOGOUT, it will be processed. On the other hand, if the initiator receives an SRP_CRED_REQ or SRP_AER_REQ before it receives a SRP_T_LOGOUT, the SRP_T_LOGOUT won't be processed. We can fix this inconsistency by changing the strategy for posting receive buffers to: * Post all receive buffers after channel establishment. * After a receive buffer has been consumed and processed, post it again. A side effect is that the ib_post_recv() call is moved out of the SCSI command processing path. Since __srp_post_recv() is not called directly any more, get rid of it and move the code directly into srp_post_recv(). Also, move srp_post_recv() up in the file to avoid a forward declaration.
