Yeah, the second patch was using an u64. I ended up using a "class" name (signalfd, timerfd, asyncfd) as dname entry. An incremental counter would not add any useful information, and noone will ever care about dentry name of those objects. Prolly the class name is the only thing you might want to know, or we can drop even that and use a shared dentry for everything. - Davide
