From 2ebc736c8452f8ccf86f5398e8d8ceec283aa50d Mon Sep 17 00:00:00 2001 From: Georg Ottinger Date: Thu, 17 Aug 2023 21:59:25 +0200 Subject: [PATCH] ext2: improve consistency of ext2_fsblk_t datatype usage The ext2 block allocation/deallocation functions and their respective calls use a mixture of unsigned long and ext2_fsblk_t datatypes to index the desired ext2 block. This commit replaces occurrences of unsigned long with ext2_fsblk_t, covering the functions ext2_new_block(), ext2_new_blocks(), ext2_free_blocks(), ext2_free_data() and ext2_free_branches(). This commit is rather conservative, and only replaces unsigned long with ext2_fsblk_t if the variable is used to index a specific ext2 block.
