Hey Linus, /* Summary */ This contains work to bring NFS connectable file handles to userspace servers. The name_to_handle_at() system call is extended to encode connectable file handles. Such file handles can be resolved to an open file with a connected path. So far userspace NFS servers couldn't make use of this functionality even though the kernel does already support it. This is achieved by introducing a new flag for name_to_handle_at(). Similarly, the open_by_handle_at() system call is tought to understand connectable file handles explicitly created via name_to_handle_at(). /* Testing */ gcc version 14.2.0 (Debian 14.2.0-6) Debian clang version 16.0.6 (27+b1) All patches are based on v6.12-rc3 and have been sitting in linux-next. No build failures or warnings were observed. /* Conflicts */ Merge conflicts with mainline ============================= No known conflicts.
