From 0df2ac59bebfac221463ef57ed3554899b41d75f Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Wed, 7 Aug 2024 13:51:38 +0200 Subject: [PATCH] tracefs: Fix inode allocation The leading comment above alloc_inode_sb() is pretty explicit about it: /* * This must be used for allocating filesystems specific inodes to set * up the inode reclaim context correctly. */ Switch tracefs over to alloc_inode_sb() to make sure inodes are properly linked.
