Just issue a readahead near the end of the vnode and enqueue an async read. Now let nfs_setattr() truncate the vnode, set its new size and nfs_vinvalbuf() waits for the pages from the readahead to become unbusy. The async read gets processed and returns with uio_resid > 0 because there is a hole and no write after the hole has been pushed yet. As the vnode size already got truncated to the new size the KASSERT() incorrectly fires. |
