Petersen" Cc: Christoph Hellwig , James Bottomley , Johannes Thumshirn , Chad Dupuis , linux-scsi@vger.kernel.org, Hannes Reinecke Hi all, here's a patchset to fixup an issue reported by QLogic: when running against a certain target the libfc stack would get in an infinite loop sending ABTS when trying to reset a connection. The problem is that the libfc stack is sending ABTS for any open exchanges when removing an rport, totally ignorant of the fact that in most cases we are already logged out of the said remote port. This patchset alters the handling slightly so that we will only ever reset open exchanges after we have either logged out of the port or an implicit logout can be assumed. With that we don't need to send ABTS any more during rport reset. As usual, comments and reviews are welcome.
