Thanks to Christoph Hellwig for the bug report. Based on feedback from Christoph and others, we may remove the need for this lookup and just pass in a file descriptor from userspace instead, and/or completely move the directory handling to userspace. For now we're just fixing the obvious bugs. Signed-off-by: J.
