Subject: scripts/decode_stacktrace.sh: fix build ID and PC source parsing
Date: Thu, 30 Oct 2025 01:03:33 +0000

Support for parsing PC source info in stacktraces (e.g. '(P)') was added in commit 2bff77c665ed ("scripts/decode_stacktrace.sh: fix decoding of lines with an additional info"). However, this logic was placed after the build ID processing. This incorrect order fails to parse lines containing both elements, e.g.:

drm_gem_mmap_obj+0x114/0x200 [drm 03d0564e0529947d67bb2008c3548be77279fd27] (P)

This patch fixes the problem by extracting the PC source info first and then processing the module build ID. With this change, the line above is now properly parsed as such:

drm_gem_mmap_obj (./include/linux/mmap_lock.h:212 ./include/linux/mm.h:811 drivers/gpu/drm/drm_gem.c:1177) drm (P)

While here, also add a brief explanation the build ID section.
