Hi Everyone,

Would it be possible to have a custom block device driver read/write
in increments of 12k instead of reading/writing data in 4k increments?
In other words, I would like to change the default page size on a
x86_64 platform (4.4.0 kernel) from 4k to 12k as the minimum page
size? I understand I may have negative performance due to
fragmentation. Any help would be appreciated.
