Field Documentation

char* abs_path

This is a redundance, it avoid the use of the d_path

struct rw_semaphore* rw_sem

This is a redundance, is a copy of the one present into the struct session_file_node, prevents a search into the rb_tree

struct file* session_filp

This is the real sense of this structure, it's a pointer pointing to the session_file, the incarnation of the original one and the core of the sessions
