What about moving the initialization of `ents` above? (Or would that
be over the line limit?)

In general, I like this change (I considered asking Nathan to do the
consolidation of declaration and initialization as you've done).  The
additional part of converting from _t to struct * is less interesting
(but still ok).  It's better to be consistent within the function
scope, but this translation unit is still a mismatch of styles.  If
the goal is to avoid typedefs, consider removing them from existence
and the required work to consistently not use them throughout this
code.

It might be over the line limit, but more importantly I prefer to have
the tracepoint fire before we start interpreting the on-disk metadata.
That way, ftrace data will show exactly where we were in the kernel
if any corruption warnings are emitted during that interpretation.

I don't think either of those two functions do that today, but I don't
want to leave a logic bomb in case they ever start doing that.

Yeah, we're slowly converting away from the _t typedefs (and other
IRIXisms) as parts of code get reworked, though of course there's
nothing obvious to suggest that this (slow transition) is in progress
nor that we're ok with the inconsistent formatting in the meantime,
which is why I accepted the original patch and added this one to do the
style conversions.

Makes sense, ents is initialized to the results of function call.
Thanks for the additional info, for accepting the earlier patch, and
this additional cleanup.
