More info on this: I can observe this bug only when piping blktrace output to blkparse. When I use temporary files all seems to be OK. Also, I found that this particular commit causes this bug: http://git.kernel.org/cgit/linux/kernel/git/axboe/blktrace.git/commit/?id=9bf422b17cb2330f94376f8ca82a6e6cc496f9a3 2016-09-28 7:56 GMT+05:00 Alexey Egorov <alex.only.d@xxxxxxxxx>: > Hello, > > I'm getting multiple entries with unordered timestamps using version > 1.1.0 of blkparse: > > $ verify_blkparse test.out > ... > Events 184855: 127 unordered, 57773 aliases > > Any chance it would be fixed?
