[PATCH 4/5] block: fix blk_rq_get_max_sectors for driver private requests

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Driver private request types should not get the artifical cap for the
FS requests.  This is important to use the full device capabilities
for internal command or NVMe pass through commands.
