From 72ea15f0ddd29b9facdab836a2f5d3e28df9b202 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 14 Dec 2022 14:43:04 -0800 Subject: fsverity: pass pos and size to ->write_merkle_tree_block fsverity_operations::write_merkle_tree_block is passed the index of the block to write and the log base 2 of the block size. However, all implementations of it use these parameters only to calculate the position and the size of the block, in bytes. Therefore, make ->write_merkle_tree_block take 'pos' and 'size' parameters instead of 'index' and 'log_blocksize'.
