[PATCH 3/8] fs: wrap simple_pin_fs/simple_release_fs arguments in a struct

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

 



Simplify passing the count and mount to simple_pin_fs and simple_release_fs,
in preparation for adding more high level operations to the simplefs API.
