Ok, now I did indeed get that

This patch can be verified with this simple test-case,
which inserts a wait loop at the bottom of 'scsih_shutdown()'
and forces SCSI commands to timeout (skip 'scmd->scsi_done()').
It abuses the 'ioc->logging_level' parameter do to that, with:

This patch adds checks for 'ioc->remove_host' in the SCSI error
handlers, so not to access pointers/resources potentially freed
in the PCI shutdown/module unload path. The error handlers may
be invoked after shutdown/unload, depending on other components.
This problem was observed with kexec on a

If you received it, just ignore it. I didn't initialize my fixes tree
correctly before pulling in Martin's branch, so it wrongly sent a patch
dropped email for every patch in the misc tree (which has already been
routed to Linus).

This is mostly updates of the usual driver suspects: arcmsr,
scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
hisi_sas. We also have a rework of the libsas hotplug handling to make
it more robust, a slew of 32 bit time conversions and fixes, and a host
of the usual minor update
