[igt-dev] [PATCH i-g-t v32 03/39] lib/igt_map: Adopt Mesa hash table
Zbigniew Kempczyński
zbigniew.kempczynski at intel.com
Mon Apr 12 11:17:32 UTC 2021
From: Dominik Grzegorzek <dominik.grzegorzek at intel.com>
The _search function has been changed to return a pointer to
the stored data instead of the entry struct. The _search_entry function,
which acts as the original search has been added. Additionally _remove function
has an optional delete_function param, to make it more usable.
For more information, see:
