BUFQ_READPRIO & BUFQ_PRIOCSCAN
I was wondering what the status of the BUFQ_READPRIO & BUFQ_PRIOCSCAN
kernel options are. The comment on all but the i386/amd64 kernel configs
are that it is experimental, whereas on i386/amd64, BUFQ_PRIOCSCAN is
enabled by default.
Does the comment need updating (I'm happy to do it) or is it deemed
experimental on anything other than i386/amd64?
I've been running the macppc 8.0_BETA kernel with the BUFQ_PRIOCSCAN
option enabled for a couple of weeks without any crashes, I/O
performance is bit of a different question in my scenario as the system
is running from a USB flash drive.
