[PATCH 1/2] tracefs: Fix inode allocation

[Mathias Krause <minipli@grsecurity.net>]

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.
