+Subject: [PATCH] [BZ 164881] hmcdrvfs: fix parsing of link count >= 1000
+From: Gerald Schaefer <gerald.schaefer@de.ibm.com>
+
+Description:  hmcdrvfs: fix parsing of link count >= 1000
+Symptom:      hmcdrvfs will ignore files with a link count >= 1000
+Problem:      The parsing code relies on having spaces between the different
+              fields in its input data. When a file has a link count >= 1000,
+              there will be no space, and the "link count" field will be
+              placed directly after the previous "mode" field. This will
+              confuse the parser, and all such files will not be accesible.
+Solution:     The "mode" field will never contain digits, so the parser can
+              recognize the "link count" field by the presence of a digit.
+Reproduction: Use a medium containing files with link count >= 1000 in
+              hmcdrvfs, and try to access/list them.
