[RFC PATCH 0/3] cxl: Fix background operation handling

[Jeongtae Park <jtp.park@samsung.com>]

Hello,

We are currently trying to add background commands like
fw-related and sanitize operation. However, as we modified 
the code, we found that there was a lot of duplication of
code, so we would like to modify the existing background 
command handling a little bit. We want to make the most of
the existing background command handling so that we can
easily add other background commands in the future.

The first patch modifies the existing sanitize operation
handling to allow other background commands to be used 
with it, and the second patch modifies sanitize to work
with the modified code. Finally, the third patch adds a
sysfs file related to the background operation. 
This sysfs entry is select/poll capable from userspace 
to notify upon completion of a background operation.

Thanks,
/jtpark
