[PATCH v2 01/17] nfit: always associate flush hints

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

 



Before enabling use of flush hints for pmem regions, we need to make
sure they are always associated.  Move the initialization of nfit_flush
out of the block-window specific init path to the general init path.
