Map name is just a hint and there is no uniqueness requirement (and also nothing in the kernel relies on map name). Everything is working based on file descriptors (FDs). When a BPF map is created, kernel returns FD to user space. User space uses that FD to identify the BPF map. > > Thanks, > > Shoaib > >
