From 490645d027c5925b30c88b9c7a663850a641d15d Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Thu, 9 Nov 2017 20:15:14 -0500 Subject: idr test suite: Fix ida_test_random() The test was checking the wrong errno; ida_get_new_above() returns EAGAIN, not ENOMEM on memory allocation failure. Double the number of threads to increase the chance that we actually exercise this path during the test suite (it was a bit sporadic before).
