Xen devel - Aug 2005 - About get_gendisk

The get_gendisk is not exported in 2.6 kernel,
So blkfront can not be made to module in 2.6
while 2.4 kernel exported get_gendisk.
Is it possible not to use get_gendisk in vbd.c?
like save gendisk in xlvbd_alloc_gendisk?

Hi Xiaofeng,

I''d suggest following the method used by other Linux disk drivers that
hook into the block layer i.e. save a reference to the gendisk in
xlbd_disk_info after allocating it. Then you don''t need to call
get_gendisk.
