lib/vsprintf: Remove support for %pF and %pf in favour of %pS and %ps
%pS and %ps are now the preferred conversion specifiers to print function names. The functionality is equivalent; remove the old, deprecated %pF and %pf support. Depends-on: commit 2d44d165e939 ("scsi: lpfc: Convert existing %pf users to %ps") Depends-on: commit b295c3e39c13 ("tools lib traceevent: Convert remaining %p[fF] users to %p[sS]") Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Petr Mladek <pmladek@suse.com> Signed-off-by: Rafael J.

-Note, that the ``F`` and ``f`` specifiers are identical to ``S`` (``s``)
-and thus deprecated. We have ``F`` and ``f`` because on ia64, ppc64 and

The ``B`` specifier results in the symbol name with offsets and should be
used when printing stack backtraces. The specifier takes into
consideration the effect of compiler optimisations which may occur
