Hey all, I noticed recently that linus/master (plus patches) stopped booting to UI on HiKey960, and I bisected the issue down to: 92170b62f1c1 ("debugfs: inode: debugfs_create_dir uses mode permission from parent")
On the HiKey960 board, we mount debugfs via: mount debugfs /sys/kernel/debug /sys/kernel/debug mode=755 But since the change, it seems most of the nodes in /sys/kernel/debug are: drwx------ Which ends up breaking the egl library, keeping it from loading. This seems to be the expected behavior of the patch, but I'm surprised the mode override is now ignored. It seems like the potential fix here would be to set the /sys/kernel/debug dir to 755 prior to mounting? Or is there some other advised solution? thanks -john
