6.6-stable review patch. If anyone has any objections, please let me know.

commit 0df2ac59bebfac221463ef57ed3554899b41d75f upstream.
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.
