Try this:
1. do a path_lookup for parent proc dir e.g. /proc/1234 and get its inode.
2. get proc_inode structure for parent from vfs inode like this:
sruct proc_inode *parent = PROC_I(inode).
PROC_I is defined in proc_fs.h
3. get parent proc_dir_entry object:
struct proc_dir_entry *parent_dir = parent->pde;
4. now you can call:
create_proc_entry("SOME file", 0644, parent_dir);
5. or you can create a directory if you want:
proc_mkdir("your dir", parent_dir);
hope this helps.
