Subject: [PATCH v1 7/7] perf symbol: Do not set binary type from symtab type
Date: Sun,  4 Oct 2026 23:34:11 -0700	[thread overview]
Message-ID: <20261005063411.114244-8-namhyung@kernel.org> (raw)
In-Reply-To: <20261005063411.114244-1-namhyung@kernel.org>

The DSO binary type is to access the binary (e.g. instruction) data
while symtab type is for the symbol table.  They may or may not be in
the same file.  We should track them separately and correctly.

As special binaries already set their type before loading symbols, leave
the binary type info and only update it when actually opening the DSO.
