Pull orangefs updates from Mike Marshall:
 "Fixes for string handling in debugfs and sysfs:

   - change scnprintf to sysfs_emit in sysfs code.

   - change sprintf to scnprintf in debugfs code.

   - refactor debugfs mask-to-string code for readability and slightly
     improved functionality"

* tag 'for-linus-6.17-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux:
  fs/orangefs: Allow 2 more characters in do_c_string()
  fs: orangefs: replace scnprintf() with sysfs_emit()
  fs/orangefs: use snprintf() instead of sprintf()
