From 58dc4ce4325108b35425ffd30e6acfad9644d49d Mon Sep 17 00:00:00 2001 From: David Sterba Date: Sun, 15 Jun 2014 00:29:04 +0200 Subject: btrfs: remove unused parameter from readahead_tree_block The parent_transid parameter has been unused since its introduction in ca7a79ad8dbe2466 ("Pass down the expected generation number when reading tree blocks"). In reada_tree_block, it was even wrongly set to leafsize. Transid check is done in the proper read and readahead ignores errors.
