lib/stackdepot: put functions in logical order
Patch series "lib/stackdepot: fixes and clean-ups", v2.
A set of fixes, comments, and clean-ups I came up with while reading
the stack depot code.
This patch (of 18):
Put stack depot functions' declarations and definitions in a more logical
order:
1. Functions that save stack traces into stack depot.
2. Functions that fetch and print stack traces.
3. stack_depot_get_extra_bits that operates on stack depot handles
and does not interact with the stack depot storage.
No functional changes.
