This is the fourth version of the patch series that makes task
management function (TMF) handling synchronous. The changes compared to
v3 of this patch series are as follows:
- The patches that are already upstream have been left out.
- Several new patches have been added.
- Facilities have been added to make debugging target drivers easier.
For certain target API misuses a warning is issued. A list of pending
commands is printed via pr_debug() if it takes too long to complete
these commands.
This patch series has been tested by running the following test
with the FCoE, iSCSI and SRP protocols:
- On a system running a debug kernel, start and configure LIO such
that it exports a RAM disk.
- On the same system, let the corresponding initiator driver log
in to LIO.
- Start multipathd, create a filesystem on the RAM disk and start
fio with data verification enabled.
- While fio is running, alternatingly submit a SCSI reset to the
initiator device (sg_reset -d) and restart the LIO stack.
