Re: [fuse-devel] Getattr called on every file following a readdir

[Pete W. <pwy...@fa...>]

Thanks, for the info and that does work.

But, is there a way to push that stat info into fuse's attribute cache
during the readdir call?  I.e., some function call like
insert_into_cache(path,  stat struct)?

Thanks, pete
