From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com> To: rostedt@goodmis.org Cc: linux-trace-devel@vger.kernel.org Subject: [PATCH v2 09/21] trace-cmd library: Bump the trace file version to 7 Date: Mon, 10 May 2021 09:16:24 +0300 [thread overview] Message-ID: <20210510061636.1794357-10-tz.stoyanov@gmail.com> (raw) In-Reply-To: <20210510061636.1794357-1-tz.stoyanov@gmail.com> Adding a compression of the trace.dat file will change its structure. These changes are not backward compatible, the old trace-cmd binaries will not be able to read compressed trace files. Bumping the version to 7 will prevent old trace-cmd to read such files.
