[PATCH v3] apparmor: test: Remove some casts which are no-longer required

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

 



With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in policy_unpack_test are no longer required.

Remove the unnecessary casts, making the conditions clearer.

This is a rebase and resend of [1], which had been accepted into the
AppArmor tree, but eventually conflicted with [2]. Let's push it via the
KUnit tree to avoid any further conflicts, as discussed in [3].

Cheers,
