Subject: reiser4: fix readpage_unix_file
From: Edward Shishkin <edward@xxxxxxxxxxx>
. If nominated (by VFS) page is out of file size, then fill it
by zeros instead of returning -EINVAL (this prevents returning
an unexpected error (-EINVAL) by some apps that don't check
file size).
. Check if the page became uptodate while it was being unlocked.
