If so, I am not sure if a mmap interface would work for DB usecase, like
PostgreSQL. I can ask.
Databases really should be using direct I/O for various reasons. And if
Postgres still isn't doing that we shouldn't work around that in the
kernel.
As I understand, direct IO support for that DB is a work-in-progress,
but if and ever it is completed I don't know.
Regardless, my plan is to work towards direct IO kernel support now.
