The calltime and rettime were used by the function graph tracer to calculate the timings of functions where it traced their entry and exit. The calltime and rettime were stored in the generic structures that were used for the mechanisms to add an entry and exit callback. Now that function graph infrastructure is used by other subsystems than just the tracer, the calltime and rettime are not needed for them. Remove the calltime and rettime from the generic fgraph infrastructure and have the callers that require them handle them. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ5Jk2BQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qr3GAQCtzSX6PYTliZKm/Wa5zhebopwhGKEb Mv0VZejaxYu0hgEA5O57J676FAOaQ7BLzoMojKFhR8RZ6LadKR5r7A0Qzgc= =Bb/r -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull fgraph updates from Steven Rostedt: "Remove calltime and rettime from fgraph infrastructure The calltime and rettime were used by the function graph tracer to calculate the timings of functions where it traced their entry and exit.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
