Module Name:    src
Committed By:   hannken

Modified Files:
        src/sys/nfs: nfs_bio.c

Log Message:
Remove an incorrect assertion.

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.
