+Subject: [procps] [Patch] Test suite fails if /proc/<pid>/smaps is absent
+Message-Id: <>
+Summary: Some Linux systems do not have /proc/<pid>/smaps, hence the test
+suite fails. Attached a patch to skip tests in that case it.
+When pmap is called with either -c, -x, or -x it tries to read
+/proc/<pid>/smaps (pmap.c, l. 540). If not present it exits.
+The file /proc/<pid>/smaps exits on Linux systems only if the kernel is
+compiled with the option CONFIG_PROC_PAGE_MONITOR (see man page proc(5)).
+In the test suite some tests check the output of pmap -X et al, but they
+fail if /proc/<pid>/smaps is not present, because pmap does not produce
+their expected output.
+Attached a patch which checks if /proc/<pid>/smaps exits, if not it
+skipps the test related to it.
+Note: It is unclear what the 'expected' behaviour/output of pmap should
+be if the file /proc/<pid>/smaps is not present. Maybe add an additional
+test to check the return code if /proc/<pid>/smaps is absent.
