Actually, the main reason I want to have GEOM backported is GBDE. Perhaps I
should just deGEOMify GEOM Based Disk Encryption. I just checked and GBDE
consists of about 2000 lines of code. Would you be interested in integrating
such deGEOMified Disk Encryption into DragonFly BSD?
As far as BUF/BIO model changes are concerned, I understand that the I/O subsystem
was supposed to be moved from KVA mapped buffers to page lists (using XIO to
manage the page lists). Have any other significant changes been made to the FreeBSD
BUF/BIO model that I should be aware of to be able to integrate deGEOMified Disk
Encryption (dGDE) into DragonFly BSD?
