Subject: NFS: Don't clear desc->pg_moreio in nfs_do_recoalesce()
X-Git-Tag: v4.2-rc5~30^2~5

NFS: Don't clear desc->pg_moreio in nfs_do_recoalesce()

Recoalescing does not affect whether or not we've already sent off
I/O, and doing so means that we end up sending a bunch of synchronous
for cases where we actually need to be using unstable writes.
