Anyone else has seen this? I did a bisect and found a commit, which I am not sure how can it impact. commit 703b5faf22fbddf984a361e6555f3a03fdba63d9 Author: George Spelvin Date:   Fri Jun 10 00:22:12 2016 -0400     fs/dcache.c: Save one 32-bit multiply in dcache lookup          Noe that we're mixing in the parent pointer earlier, we     don't need to use hash_32() to mix its bits.  Instead, we can     just take the msbits of the hash value directly.          For those applications which use the partial_name_hash(),     move the multiply to end_name_hash.          Signed-off-by: George Spelvin     Signed-off-by: Linus Torvalds Thanks, Srinivas
