function _node_access_rebuild_batch_operation

Implements callback_batch_operation().

Performs batch operation for node_access_rebuild().

This is a multistep operation: we go through all nodes by packs of 20. The batch processing engine interrupts processing and sends progress feedback after 1 second execution time.

Parameters

array $context: An array of contextual key/value information for rebuild batch process.
