On architectures with large pages (like\n64KB on ppc64le), the test's hardcoded request for 32769 pages results\nin a ~2GB mapping. So in suse test system configured with 2GB of RAM and\nno swap space, the test will fails with following information:\n\nmmapstress06: errno = 12; large mmap failed\nfor this test to run, it needs a mmap space of\n32769 pages\n\nThe failure occurs because the 2GB request cannot be fulfilled within\nthe 2GB RAM limit without swap backing. Since the test specifically\nintends to exercise swap-related logic (mfile_swap), it should be skipped\nwith TCONF when the system lacks swap space.\n\nSigned-off-by: Wei Gao \n---\n testcases/kernel/mem/mmapstress/mmapstress06.c | 8 ++++++++\n 1 file changed, 8 insertions(+)","diff":"diff --git a/testcases/kernel/mem/mmapstress/mmapstress06.c b/testcases/kernel/mem/mmapstress/mmapstress06.c\nindex 37b7edc84..54b5febbf 100644\n--- a/testcases/kernel/mem/mmapstress/mmapstress06.c\n+++ b/testcases/kernel/mem/mmapstress/mmapstress06.c\n@@ -51,6 +51,8 @@ void ok_exit();\n \n #define ANON_GRAN_PAGES_MAX\t(32U)\n \n+#include \"tst_memutils.h\"\n+\n extern time_t time(time_t *);\n extern char *ctime(const time_t *);\n extern int atoi(const char *);\n@@ -74,6 +76,12 @@ int main(int argc, char *argv[])\n \t\t(void)fprintf(stderr, \"usage: %s sleep_time\\n\", argv[0]);\n \t\tanyfail();\n \t}\n+\n+\tif (tst_available_swap() <= 0) {\n+\t\ttst_resm(TCONF, \"Test requires swap space to exercise mfile_swap logic\");\n+\t\ttst_exit();\n+\t}\n+\n \t(void)time(&t);\n // (void)printf(\"%s: Started %s\", argv[0], ctime(&t)); LTP Port\n \tif (sbrk(pagesize - ((ulong) sbrk(0) & (pagesize - 1))) == (char *)-1) {\n","prefixes":["v1"]}
