Subject: [PATCH v3 4/9] sched/vtime: Move vtime accounting external declarations above inlines
Date: Thu, 15 Apr 2021 15:21:01 -0700
Message-ID: <20210415222106.1643837-5-seanjc@google.com> (raw)
In-Reply-To: <20210415222106.1643837-1-seanjc@google.com>

Move the blob of external declarations (and their stubs) above the set of
inline definitions (and their stubs) for vtime accounting.  This will
allow a future patch to bring in more inline definitions without also
having to shuffle large chunks of code.

No functional change intended.
