- Fix register_snapshot_trigger() on allocation error
If the snapshot fails to allocate, the register_snapshot_trigger() can
still return success. If the call to tracing_alloc_snapshot_instance()
returned anything but 0, it returned 0, but it should have been returning
the error code from that allocation function.
- Remove leftover code from tracefs doing a dentry walk on remount.
The update_gid() function was called by the tracefs code on remount
to update the gid of eventfs, but that is no longer the case, but that
code wasn't deleted. Nothing calls it. Remove it.

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 Restructured Text 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.
