From 4d231b91a944f3cab355fce65af5871fb5d7735b Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Wed, 21 Aug 2024 12:23:22 -0300 Subject: ext4: return error on ext4_find_inline_entry In case of errors when reading an inode from disk or traversing inline directory entries, return an error-encoded ERR_PTR instead of returning NULL. ext4_find_inline_entry only caller, __ext4_find_entry already returns such encoded errors.
