commit8fa4592a14upstream. If all other conditions in nfs_can_extend_write() are met, and there are no locks, then we should be able to assume close-to-open semantics and the ability to extend our write to cover the whole page. With this patch, the xfstests generic/074 test completes in 242s instead of >1400s on my test rig.
