What is the best way from inside the kernel, to find the dentry that another dentry points to via symlink?
Scenario:
I have a kobj of a device in the sysfs system. Inside a directory of the kobj, is a symlink to another device I need to get. I can find the dentry of the symlink, but I haven't found a good way to get to the dentry of what the symlink points to.
Is there a standard way to do this, or do I need to start hacking at the follow_link of the sysfs directory to get what I want?
Do I need to hack up something like page_readlink to get the path, and then do vfs_follow_link to get the rest. Another thing is that I can't rely on what current->fs points to.
Thanks,
-- Steve
