Git bisect blames the following: commit b42bf88828cde60772dc08201d0a4f1a0663d7bc CIFS: Implement follow_link for SMB2 Author: Pavel Shilovsky dmesg doesn't complain at all. Reverting the commit fixes the problem and the deduplicated files can be opened perfectly, but more recent updates have been made on top of that one and i think it can't be cleanly reverted on current -next trees (or rcs) If i'm not mistaken, windows 2012 treats deduplicated files as links, but that's just what i can surmise from using it, i haven't read anything about it's internals yet. I've CC'ed the persons mentioned on the patch, please forward it to anyone else that might be interested and is not on the lkml. Thanks, Joao Correia
