Christian Brauner 4d80aaebcf fs: make helpers idmap mount aware
Extend some inode methods with an additional user namespace argument. A
filesystem that is aware of idmapped mounts will receive the user
namespace the mount has been marked with. This can be used for
additional permission checking and also to enable filesystems to
translate between uids and gids if they need to. We have implemented all
relevant helpers in earlier patches.

As requested we simply extend the exisiting inode method instead of
introducing new ones. This is a little more code churn but it's mostly
mechanical and doesnt't leave us with additional inode methods.

Real-Time Executive for Multiprocessing Systems (RTEMS)
-------------------------------------------------------

RTEMS, Real-Time Executive for Multiprocessor Systems, is a real-time executive
(kernel) which provides a high performance environment for embedded
applications with the following features:

 - standards based user interfaces
 - multitasking capabilities
 - homogeneous and heterogeneous multiprocessor systems
 - event-driven, priority-based, preemptive scheduling
 - optional rate monotonic scheduling
 - intertask communication and synchronization
 - priority inheritance
 - responsive interrupt management
 - dynamic memory allocation
 - high level of user configurability
 - open source with a friendly user license
