Subject: [PATCH v2 01/13] kho: Fix misleading log message in kho_populate()
Date: Fri, 14 Nov 2025 13:59:50 -0500	[thread overview]
Message-ID: <20251114190002.3311679-2-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20251114190002.3311679-1-pasha.tatashin@soleen.com>

The log message in kho_populate() currently states "Will skip init for
some devices". This implies that Kexec Handover always involves
skipping device initialization.

However, KHO is a generic mechanism used to preserve kernel memory across
reboot for various purposes, such as memfd, telemetry, or reserve_mem.
Skipping device initialization is a specific property of live update
drivers using KHO, not a property of the mechanism itself.

Remove the misleading suffix to accurately reflect the generic nature of
KHO discovery.
