Hi folks,
This following series is destined for v3.7-rc1 code, and re-adds support for
buffered FILEIO + emulate_write_cache=1 emulation removed in v3.5, as well as
fixing up a long standing issue wrt to MaxRecvDataSegmentLength handling within
iscsi-target code.
The latter bit is the bulk of the series that involves adding a proper
configurable MaxXmitDataSegmentLength TPG parameter configfs attr, and converts
iscsi-target login logic, incoming PDU payload checks, TMR TASK_REASSIGN ops, and
non contigious sequence+pdu operation to now honor MXDSL.
Open-iSCSI + Linux-iSCSI folks please review the MXDSL bits, and please let us
know if you have any concerns.
Thank you!
