Rob Norris b9c45fe68c Linux: zfs_putpage: complete async page writeback immediately ... For async page writeback, we do not need to wait for the page to be on disk before returning to the caller; it's enough that the data from the dirty page be on the DMU and in the in-memory ZIL, just like any other write. So, if this is not a syncing write, don't add a callback to the itx, and instead just unlock the page immediately. (This is effectively the same concept used for FreeBSD in d323fbf49c).
