After checking all possible call chains to dev_pm_opp_init_cpufreq_table() here, my tool finds that this function is never called in atomic context, namely never in an interrupt handler or holding a spinlock. And dev_pm_opp_init_cpufreq_table() calls dev_pm_opp_get_opp_count(), which calls mutex_lock that can sleep. It indicates that atmtcp_v_send() can call functions which may sleep. Thus GFP_ATOMIC is not necessary, and it can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself.
