What about P9_FID_XATTR, seems like we have the same issue there too?

wstat, lock, and getlock need closer auditing and perhaps fixing.


Sorry, forgot to hit reply-to-all.
Yes, it is probable that those functions will suffer from the same bug.
I will have to study XATTR and see how that will be affected. I don't know whether it is possible for these functions to be called for XATTR, and if it is then I do not know the proper way to handle it.
Perhaps we should have some function or macro to obtain the correct FD from an fidp structure, which could be used for fsync, wstat, lock and getlock?
