Subject: [PATCH v2 07/47] xfs: add function pointers for get/update keys to the btree
Date: Thu, 28 Jul 2016 12:46:15 -0700	[thread overview]
Message-ID: <20160728194615.GA15746@birch.djwong.org> (raw)
In-Reply-To: <146907700604.25461.2181974283557088355.stgit@birch.djwong.org>

Add some function pointers to bc_ops to get the btree keys for
leaf and node blocks, and to update parent keys of a block.
Convert the _btree_updkey calls to use our new pointer, and
modify the tree shape changing code to call the appropriate
get_*_keys pointer instead of _btree_copy_keys because the
overlapping btree has to calculate high key values.
