[GIT PULL v2] tracefs: Updates for v7.1

[Steven Rostedt]

Linus,

tracefs updates for 7.1:

- Simplify error handling with guards()

  Use guards() to simplify the handling of releasing locks in exit paths.

- Use dentry name snapshots instead of allocation

  Instead of allocating a temp buffer to store the dentry name to use in
  mkdir() and rmdir() use take_dentry_name_snapshot().

- Fix default permissions not being applied at boot

  The default permissions for tracefs was 0700 to only allow root having
  access. But after a change to fix other mount options the update to
  permissions ignored the defined default and used the system default of
  0755. This is a regression and is fixed.

Changes since v1: https://lore.kernel.org/all/20260414075753.2a036358@robin/

- Removed unused 'ret' variable in eventfs_iterate()
