linux/torvalds@11068e0b64 removes it, suggesting this was a always there as a helper to handle concurrent seeks, which all filesystems now handle themselves if necessary. Without looking into the mechanism, I can imagine how it might have been used, but we have always set it to zero and never read from it, presumably because we've always tracked per-caller position through the znode anyway. So I don't see how there can be any functional change for us by removing it. I've stayed conservative though and left it in for older kernels, since its clearly not hurting anything there.
