This patch changes some 400 lines, most if not all of which get longer
and more complicated to read. 23 get sufficiently longer to require an
additional linebreak. I can't remember complexity being invited into
the kernel without good reasoning, yet the patch description is
surprisingly low on reasoning:
> Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
The following two patches manage to remove 7 lines in total. In total
23 were added, 7 removed , 400+ made longer and more complicated. Is
there another more favorable metric? Will this patchset prevent bugs?
Shrink the kernel size? Anything?
If churn is the only effect of this, please considere it NAKed again.
