7303515ae4 Documentation: Clarify f_cred vs current_cred() use
When making access control choices from a file-based context, f_cred
must be used instead of current_cred() to avoid confused deputy attacks
where an open file may get passed to a more privileged process. Add a
short paragraph to explicitly state the rationale.

806654a966 Documentation: Use "while" instead of "whilst"
Whilst making an unrelated change to some Documentation, Linus sayeth:

  | Afaik, even in Britain, "whilst" is unusual and considered more
  | formal, and "while" is the common word.
  |
  | [...]
  |
  | Can we just admit that we work with computers, and we don't need to
  | use þe eald Englisc spelling of words that most of the world never
  | uses?

dictionary.com refers to the word as "Chiefly British", which is
probably an undesirable attribute for technical documentation.

Replace all occurrences under Documentation/ with "while".

0b345d722e Documentation: security/credentials.rst: explain need to sort group_list
This patch updates the documentation with the observations that led
to commit bdcf0a423e ("kernel: make groups_sort calling a
responsibility group_info allocators") and the new behaviour required.
Specifically that groups_sort() should be called on a new group_list
before set_groups() or set_current_groups() is called.
