Sorry about the late reply. I am on vacation now.

Personally, I use "== NULL" or "!= NULL" on purpose, since it is more 
emphasized than the checkpatch.pl suggested way, and I tend to use the nullptr explicitly.

BTW, It seems other filesystems still use "== NULL" or "!= NULL" explicitly, too, eg:
xfs, ext4, ext2, ocfs2, etc... You could 'grep' in the fs directory... 

Other commits look good for me at glance.

Thanks,
