[00/18] lightnvm: next set of improvements for 5.2

Message

This is another set of fixes and improvements to both pblk and lightnvm
core. 

First patch fixes an issue related to format specifier introduced in
previous series (reported by 0-day). Second patch is another leftover from
previous patchset, since we decided to reorganize it a little. Third patch is
the most crutial, since it changes the approach to partial read path, so
detailed review is needed especially here.

Other patches are my other findings related to some bugs or potential
improvements, mostly related to some corner cases, so with a lower
priority to review for now.

I did some testing with QEMU, but as always feedback and testing is
appreciated.
