2. SYNOPSIS ▲
struct dentry * debugfs_rename(struct dentry * old_dir , struct dentry * old_dentry , struct dentry * new_dir , const char * new_name );
3. ARGUMENTS ▲
a pointer to the parent dentry for the renamed object. This should be a directory dentry.
dentry of an object to be renamed.
a pointer to the parent dentry where the object should be moved. This should be a directory dentry.
a pointer to a string containing the target name.
4. DESCRIPTION ▲
This function renames a file/directory in debugfs. The target must not exist for rename to succeed.
This function will return a pointer to old_dentry (which is updated to reflect renaming) if it succeeds. If an error occurs, NULL will be returned.
If debugfs is not enabled in the kernel, the value -ENODEV will be returned.
