From: Srish Srinivasan <ssrish@linux.ibm.com>
Date: 2026-08-27 06:23:58
Also in:
keyrings, linux-integrity, linuxppc-dev, lkml
Subsystem:
documentation, linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Jonathan Corbet, Madhavan Srinivasan, Linus Torvalds
Wrap long PKS hcall return-value lines consistently and fix a typo in the
H_PKS_UNWRAP_OBJECT description.
Also update the MAINTAINERS entry from KEYS-TRUSTED-PLPKS to
KEYS-TRUSTED-PKWM to reflect the PowerVM Key Wrapping Module naming.
Fixes: 133aa79e211d ("pseries/plpks: add HCALLs for PowerVM Key Wrapping Module")
Fixes: c99fcb0d735b ("keys/trusted_keys: establish PKWM as a trusted source")
