[PATCH v5 0/2] Delete task_euid()

[Alice Ryhl <aliceryhl@google.com>]

The task_euid() method is a very weird method, and Binder was the only
user. As of commit 65b672152289 ("binder: use current_euid() for
transaction sender identity") Binder doesn't use task_euid() anymore,
so we can delete this method.

My suggestion would be to merge this through the LSM tree.
