Subject: [PATCH 1/6] trace-cmd library: Bump the trace file version to 7
Date: Thu, 22 Apr 2021 10:17:13 +0300 [thread overview]
Message-ID: <20210422071718.483383-2-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210422071718.483383-1-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.
