From 153498f200d295f3efa6bd37fc6e7ff105ab344f Mon Sep 17 00:00:00 2001 From: Yu Peng Date: Tue, 19 May 2026 16:34:09 +0800 Subject: tracing: Use krealloc_array() for trace option array growth Use krealloc_array() when growing tr->topts instead of open-coding the size calculation in krealloc(). This makes the resize path use the helper intended for array allocations and avoids manual multiplication of the element count and element size.
