The patch titled
knfsd: exportfs: move acceptable check into find_acceptable_alias
has been removed from the -mm tree. Its filename was
knfsd-exportfs-move-acceptable-check-into-find_acceptable_alias.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: knfsd: exportfs: move acceptable check into find_acceptable_alias
From: Christoph Hellwig <hch@xxxxxxxxxxxxx>
All callers of find_acceptable_alias check if the current dentry is acceptable
before looking for other acceptable aliases using find_acceptable_alias. Move
the check into find_acceptable_alias to make the code a little more dense and
add a comment to find_acceptable_alias that documents its intent.
