Changeset 1eecbcdca2bd ("docs: move protection-keys.rst to the core-api book")
from Jun 7, 2019 converted protection-keys.txt file to ReST.
A recent change at protection_keys.c partially reverted such
changeset, causing it to point to a non-existing file:
- * Tests x86 Memory Protection Keys (see Documentation/core-api/protection-keys.rst)
+ * Tests Memory Protection Keys (see Documentation/vm/protection-keys.txt)
It sounds to me that the changeset that introduced such change
4645e3563673 ("selftests/vm/pkeys: rename all references to pkru to a generic name")
could also have other side effects, as it sounds that it was not
generated against uptream code, but, instead, against a version
older than Jun 7, 2019.

Thanks for finding this! The patch set which moved protection-keys.txt
out of x86 code probably just missed this when it got rebased. It
originated well before June 2019, iirc.

That's right. Sorry about that. Must have missed it when rebasing the
older pkey selftest patches. Thanks for fixing this Mauro.

This commit didn't land in Linux 5.7-rc4 yet looks like. Probably in mm
or doc tree and has dependency on it?
