9pfs: disable msize warning for synth driver (2020-09-15 12:12:03 +0200)
----------------------------------------------------------------
The intention of the following two patches is making users aware about
the negative file I/O performance impact when using a very low value
for 9P client parameter 'msize', which especially is the case if no
'msize' parameter was supplied by the user with a 9P Linux client at all.
All it does is logging a performance warning on host side (once) in
that case. By setting 'msize' on client side to any value larger than
8192 the performance warning will disappear.
See https://wiki.qemu.org/Documentation/9psetup#msize for details.
----------------------------------------------------------------

9pfs: log warning if msize <= 8192
