NFSv4.2: Serialise O_DIRECT i/o and fallocate()
[ Upstream commit b93128f29733af5d427a335978a19884c2c230e2 ]
Ensure that all O_DIRECT reads and writes complete before calling
fallocate so that we don't race w.r.t. attribute updates.
Fixes: 99f237832243 ("NFSv4.2: Always flush out writes in nfs42_proc_fallocate()")
