There are some applications that write to predefined non-overlapping file offsets from multiple clients and therefore don't need to rely on file locking. However, if these applications want non-aligned offsets and sizes they need to either use locks or risk data corruption, as the NFS client defaults to extending writes to whole pages. This commit adds a new mount option `noalignwrite`, which allows to turn that off and avoid the need of locking, as long as these applications don't overlap on offsets.

The new name seems a better choice. I'm also on Christoph's camp that having this behavior be the default makes sense given that we have large folios. Reviewed-by: Sagi Grimberg <sagi@xxxxxxxxxxx> Trond, Anna, What are your thoughts on this?
