aaf96673e6 scst: Unbreak the UEK 4 build 
UEK 4 RPMs like kernel-uek-4.14.35-2025.402.2.1.el7uek.x86_64 include a
backport of cpu_to_be32_array() and kvcalloc(). Hence disable the SCST
backports for these functions when building against UEK 4.

143e9c9684 ib_srpt: Use a workqueue for processing RDMA completions 
Use a workqueue for processing RDMA completions instead of creating one
kernel thread per RDMA channel. This change improves performance if the
number of RDMA channels is large by reducing the number of context
switches between kernel threads while processing RDMA completions. An
additional change is that srpt_set_ch_state() no longer wakes up the
RDMA completion context but that srpt_cm_rtu_recv() wakes up the RDMA
completion context instead.

a3266ca8f2 scstadmin: Remove support for the "new" sysfs interface 
Around 2011 a sysfs-tree-changes branch was created in the SourceForge
repository because Greg KH asked to rework the SCST sysfs interface. That
interface is called the "new" sysfs interface. The current and only used
API is called the "old" sysfs interface. Since the "new" sysfs interface
never had any users other than myself, remove support for that interface.

See also commit a66cbc4115 ("scstadmin: Add support for the sysfs
interface provided by the code on the sysfs-tree-changes branch").

9b2f2a4a71 qla2x00t-32gbit: Revert "Disable T10-DIF feature with FC-NVMe during probe" 
FCP T10-PI and NVMe features are independent of each other. This patch
allows both features to co-exist.

This reverts commit 5da05a26b8305a625bc9d537671b981795b46dab.

05cc5a7aab qla2x00t-32gbit: Fix null pointer access during disconnect from subsystem 
NVMEAsync command is being submitted to QLA while the same NVMe controller
is in the middle of reset. The reset path has deleted the association and
freed aen_op->fcp_req.private. Add a check for this private pointer before
issuing the command.
