However, currently, alarm API uses rte_malloc to allocate memory,\nwhich will create a circular dependency between alarm API and memory\nsubsystem.\n\nTo avoid such chicken and egg dilemma, we change to use glibc malloc\nin the alarm API.\n\nSigned-off-by: Jianfeng Tan <jianfeng.tan@intel.com>\nSigned-off-by: Anatoly Burakov <anatoly.burakov@intel.com>\n---\n lib/librte_eal/linuxapp/eal/eal_alarm.c | 9 ++++-----\n 1 file changed, 4 insertions(+), 5 deletions(-)",
