> Fairly straightforward, no?
So, I've finished the series today. It took a while because I wanted to
hammer on it with stress-ng --{procfs,pidfd}, run LTP, and then do some
other tests. It survives everything now for over 24h. There were a few
bugs as expected in the first draft.
@Linus, if you're up for it, please take a look at:
https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git vfs.pidfd
The topmost 6 commits contain everything we've had on here. I renamed
pidfdfs to pidfs and all helpers completely mechanically. The rest is
unchanged. At the end we have the conversion fo path_from_stashed(). And
the topmost commit implements your suggestion. Let me know if your ACK
still stands.
