The patch titled
knfsd: nfsd: make exp_rootfh handle exp_parent errors
has been removed from the -mm tree. Its filename was
knfsd-nfsd-make-exp_rootfh-handle-exp_parent-errors.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: knfsd: nfsd: make exp_rootfh handle exp_parent errors
From: J.Bruce Fields <bfields@xxxxxxxxxxxx>
Since exp_parent can fail by returning an error (-EAGAIN) in addition to by
returning NULL, we should check for that case in exp_rootfh.
(TODO: we should check that userland handles these errors too.)
