5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@xxxxxxxxxx>
[ Upstream commit d3aefd2b29ff5ffdeb5c06a7d3191a027a18cdb8 ]
If the namespace doesn't match the one in "net", then we'll continue,
but that doesn't cause another rhashtable_walk_next call, so it will
loop infinitely.
Fixes: ce502f81ba88 ("NFSD: Convert the filecache to use rhashtable")
