Hi! I noticed that open_tree() doesn't have a manpage yet; and while looking for a WIP manpage on the lists, I found this mail, which is from February, submits manpages for open_tree() and other related syscalls, and doesn't seem to have a response from you: https://lore.kernel.org/linux-fsdevel/20200207174236.18882-1-pvorel@xxxxxxx/ I wonder whether maybe you haven't seen that mail in the first place. It was addressed to linux-man@xxxxxxxxxxxxxxx as "To" and mtk.manpages@xxxxxxxxx as "Cc", which is the reverse of what's suggested at <https://www.kernel.org/doc/man-pages/patches.html>... maybe that runs into some filter on your side? Or maybe it just landed in a spam filter somewhere or something like that?
