[for-linus][PATCH 3/9] tracefs: Fix inode allocation

From: Steven Rostedt
Date: Thu Aug 08 2024 - 10:21:48 EST


From: Mathias Krause <minipli@xxxxxxxxxxxxxx>

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.
