[PATCH v2 0/2] usercopy: Convert test_user_copy to KUnit test

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

 



Hi,

This builds on the proposal[1] from Mark and lets me convert the
existing usercopy selftest to KUnit. Besides adding this basic test to
the KUnit collection, it also opens the door for execve testing (which
depends on having a functional current->mm), and should provide the
basic infrastructure for adding Mark's much more complete usercopy tests.

 v2:
 - dropped "initial VMA", turns out it wasn't needed (Mark)
 - various cleanups in the test itself (Vitor)
 - moved new kunit resource to a separate file (David)
 v1: https://lore.kernel.org/all/20240519190422.work.715-kees@xxxxxxxxxx/
