[PATCH 0/3] media: Optimize the code using vmalloc_array

Posted by tanze 3 months, 2 weeks ago

Change array_size() to vmalloc_array(), Due to vmalloc_array() is optimized better,
uses fewer instructions, and handles overflow more concisely

Hi, dear maintainer

These patches have had their v2 versions sent because the CI robot
