But we are not + resetting inflight message state. + + In extreme corner case where we sent message to FSP via fsp_sync_msg() path + and FSP Reset/Reload happens before getting respose from FSP, then we will + endup waiting in fsp_sync_msg() until everything becomes normal. + + This patch adds fsp_in_rr() check to fsp_sync_msg() and return error to caller + if FSP is in R/R. |
