[PATCH 1/9] null_blk: adjust null_param_store_val()

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

 



Move null_param_store_val() top of all the module parameter decalrations
so it can be used by next patches in this series, also while at it
rename this function to null_param_store_int() since it is only
validating values of type int and not generic one.

No functional change in this pacth.
