Rot.
Places in nfsd must be fixed, LSM hooks *moved* *to* *callers*. And
really, by that point I absolutely do not give a damn for these clowns.
"Help with merging" implies that they can't be arsed to do _anything_
with their code. Just as they could not be arsed to react to any
comments (including civil ones) in any manner except "wait for a month
and repost without changes". Sod them.
And no, "make static where all (two of) current callers have vfsmount"
is non-starter. path_...() is (at most) a convenience helper, not a
fundamental interface - simply because new callers should not be
forced into inventing a fake vfsmount just to use that.
I'll look into missing mnt_..._write() in nfsd and fix that. The rest...
Sorry.
