Subject: Re: [PATCH -next 0/3] cleanup of devtmpfs_*_node()

The test steps:
1. Set the SElinux label of /dev to user_home_t 
2. modprobe zram num_devices=1000

The above test result is that there is no zram device was found in the 
/dev. And don't see any errors printed in jouranls/dmesg. Of course, 
it is rare to create 1000 zram devices, use dev_err may be better.

Longlong Xia (3):
  devtmpfs: add debug info to handle()
  driver core: add error handling for devtmpfs_create_node()
  devtmpfs: remove return value of devtmpfs_delete_node()
