Bisection led to "NFS: Fix O_DIRECT locking issues" (upstream commit
7c6339322ce0c6128acbe36aacc1eeb986dd7bf1). Reverting that patch and
"NFS: Fix error handling for O_DIRECT write scheduling" (upstream
commit 954998b60caa8f2a3bf3abe490de6f08d283687a) (not a clean revert
this one) made ltp-dio pass again.
