While profiling the cxlflash_queuecommand() path under a heavy load it
was found that number of retries to find cmd_room was fairly high.
There are two problems with the current back-off:
a) It starts with a udelay of 0
b) It backs-off linearly
Tried several approaches (a

This series has a couple of patches in cxlflash.
The first patch is critical as it fixes a regression that was introduced
by Commit 6ded8b3cbd9a ("cxlflash: Unmap problem state area before
detaching master context") as part of the first SCSI push for v4.6.
The second patch addresses a performance

At current irq_set_affinity_notifier() implementation, it has two meaning;
set and clear notify. To be more clear, separate it into two;
irq_set_affinity_notifier() and irq_del_affinity_notifier().
At irq_set_affinity_notifier() function, no longer might_sleep() function
is called unnecessarily a
At current implementation, it only supports one IRQ notifier for irq_desc.
When if we try to register another IRQ notifier, it automatically
un-register previous one and register new one. With this patch, multiple
IRQ notifier is supported.

Each irq_desc only supports one IRQ affinity notifier at current
implementation so when we try to register another notifier, it silently
unregister previous entry and register new one.
However the problem is that if CONFIG_RFS_ACCEL is set, at current
implementation no way to set additional IRQ af
