NAME
debugfs_rename - rename a file/directory in the debugfs filesystemSYNOPSIS
- struct dentry * debugfs_rename(struct dentry * old_dir, struct dentry * old_dentry, struct dentry * new_dir, const char * new_name);
ARGUMENTS
old_dir
- a pointer to the parent dentry for the renamed object. This should be a directory dentry.
old_dentry
- dentry of an object to be renamed.
new_dir
- a pointer to the parent dentry where the object should be moved. This should be a directory dentry.
new_name
- a pointer to a string containing the target name.
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.
