Hi,
thanks for your patch! But please add a short patch description (beside
the subject), e.g. "Change the name of some variables so that the code
can be compiled with -Wshadow, too".
And you've got to put a "Signed-off-by" line at the end of the patch
description, too. See this URL for details:
https://wiki.qemu.org/Contribute/SubmitAPatch#Patch_emails_must_include_a_Signed-off-by:_line
For future patches to files in the linux-user directory, please also CC:
the maintainers of this subsystem (i.e. Ruku Voipio and Laurent Vivier,
see MAINTAINERS file).
Thanks,
Thomas

Thomas already gave you some hints what to improve. I'd just like to add
that you shouldn't send the email to the qemu-block mailing list if the
patch is not about the block layer at all.

Sorry, I am a newbie. I have never used this kind of thing before.
I will definitely pay attention next time.
