[GIT PULL] x86/cache for v7.1-rc1

From: Borislav Petkov

Date: Mon Apr 13 2026 - 15:11:40 EST


Hi Linus,

please pull the x86 resctrl lineup for v7.1-rc1.

Btw, this is my first pull request text using AI. It is ok-ish but it was too
much bla so I had to shorten it into sanity. Some of the formulations are
still "too much" but I'll be even more strict with the next ones.

:-)

Thx.

fs/resctrl: Add missing return value descriptions (2026-04-07 21:01:22 +0200)

----------------------------------------------------------------
— Add return value descriptions to several internal functions, addressing
kernel-doc complaints

— Add the x86 maintainer mailing list to the resctrl section so they are
automatically included in patch submissions, and reference the applicable
contribution rules document

— Allow users to apply a single Capacity Bitmask to all cache domains at once
using '*' as a shorthand, instead of having to specify each domain
individually. This is particularly user-friendly on high core-count systems
with many cache clusters

- When a user provides a non-existent domain ID while configuring cache
allocation, ensure the failure reason is properly reported to the user
rather than silently returning an error with a misleading "ok" status
