6.9-stable review patch. If anyone has any objections, please let me know.

commit 302e9dca8428979c9c99f2dbb44dc1783f5011c3 upstream.
If we somehow attempt to read beyond the directory size, an error is supposed to be returned.
However, in some cases, read requests do not stop and instead enter into a loop.
To avoid this, we set the position in the directory to the end.
