Data Fields
struct m0_be_btree *	ba_tree
struct m0_buf	ba_value
bool	ba_write

Detailed Description

Btree anchor, used to perform btree inplace operations in which values are not being copied and the ->bb_lock is not released until m0_be_btree_release() is called.

In cases, when data in m0_be_btree_anchor::ba_value is updated, m0_be_btree_release() will capture the region data lies in.
