Re: Does btrace dump actual i/o data?

[Vasily Tarasov <tarasov@xxxxxxxxxxx>]

blktrace does not support dumping a request's data. But it seems that
you can use other tools in your case. E.g.,  if it is a user-space
process writing to a fake file, then you can use  "strace" to capture
complete arguments of every system call.
