3 years ago Can you check if there is any memory leak on your system?
CONFIG_HAVE_DEBUG_KMEMLEAK=y CONFIG_DEBUG_KMEMLEAK=y CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE=16000
Check dmesg for kmemleak messages. You will see memleak: Kernel memory leak detector initialized (mem pool available: 15526) kmemleak: Automatic memory scanning thread started
Then, cat /sys/kernel/debug/kmemleak

3 years ago I think there is no memory leak.
