From 32f98aab75dd385e326c975717f8b730c6c57508 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 7 Oct 2016 16:42:25 +0300 Subject: perf intel-pt/bts: Tidy instruction buffer size usage Tidy instruction buffer size usage in preparation for copying the instruction bytes onto samples. The instruction buffer is presently used for debugging, so rename its size macro from INTEL_PT_INSN_DBG_BUF_SZ to INTEL_PT_INSN_BUF_SZ, and use it everywhere. Note that the maximum instruction size is 15 which is a less efficient size to copy than 16, which is why a separate buffer size is used.
