Meanwhile, unix_release_sock() clears u->path under\nunix_state_lock() and drops the path reference after unlocking.\n\nRead the inode and device numbers for UNIX_DIAG_VFS while holding\nunix_state_lock(), then emit the netlink attribute after dropping the\nlock.\n\nThis keeps the VFS data stable while the reply is being built.",
