NAME¶
debugfs_create_symlink - create a symbolic link in the debugfs filesystem
SYNOPSIS¶
struct dentry * debugfs_create_symlink(const char * name, struct dentry * parent, const char * target);
ARGUMENTS¶
name
a pointer to a string containing the name of the symbolic
link to create.
parent
a pointer to the parent dentry for this symbolic link.
This should be a directory dentry if set. If this paramater is NULL, then the
symbolic link will be created in the root of the debugfs filesystem.
target
a pointer to a string containing the path to the target
of the symbolic link.
DESCRIPTION¶
This function creates a symbolic link with the given name in debugfs that links to the given target path.
This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_remove function when the symbolic link is to be removed (no automatic cleanup happens if your module is unloaded, you are responsible here.) If an error occurs, NULL will be returned.
If debugfs is not enabled in the kernel, the value -ENODEV will be returned.
