Sounds good, attached is updated patch #2:
[PATCH 2/2] [block]: Add SG_IO device check in refresh_total_sectors()
Also, I am using the options in .vimrc to follow QEMU's indent style:
set smartindent
set tabstop=4
set shiftwidth=4
set expandtab
I assume this is what should be used when sending QEMU patches, yes..?
Best,
