When looking at the conflict, I looked at that part of
vfs_clone_file_prep_inodes(), and reacted to the insanity.
WTF?
/* Zero length dedupe exits immediately; reflink goes to EOF. */
if (*len == 0) {
if (is_dedupe) {
*len = 0;
return 0;
}
*len = isize - pos_in;
}
I'll just leave you to read through that part a bit more. Because
there are two completely insane things going on in that code sequence.
