NAME¶
debugfs_create_dir - create a directory in the debugfs filesystem
SYNOPSIS¶
struct dentry * debugfs_create_dir(const char * name, struct dentry * parent);
ARGUMENTS¶
name
a pointer to a string containing the name of the
directory to create.
parent
a pointer to the parent dentry for this file. This should
be a directory dentry if set. If this paramater is NULL, then the directory
will be created in the root of the debugfs filesystem.
DESCRIPTION¶
This function creates a directory in debugfs with the given name.
This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_remove function when the file 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.
