NAME

debugfs_rename - rename a file/directory in the debugfs filesystem  

SYNOPSIS

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.
