zfs_putpages() would put the entire range of pages onto the ZIL, then return VM_PAGER_OK for each page to the kernel. However, an associated zil_commit() or txg sync had not happened at this point, so the write may not actually be on disk. So, we rework it to use a ZIL commit callback, and do the post-write work of undirtying the page and signaling completion there. We return VM_PAGER_PEND to the kernel instead so it knows that we will take care of it. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.
