+Subject: ext4: free orphan info with kvfree
+
+From: Jan Kara <jack@suse.cz>
+
+commit 971843c511c3c2f6eda96c6b03442913bfee6148 upstream.
+
+Orphan info is now getting allocated with kvmalloc_array(). Free it with
+kvfree() instead of kfree() to avoid complaints from mm.
+
+Reported-by: Chris Mason <clm@meta.com>
+Fixes: 0a6ce20c1564 ("ext4: verify orphan file size is not too big")
