Subject: [PATCH v2] Drivers: hv: Use better errno matches for HV_STATUS values
Date: Mon, 6 Oct 2025 23:08:08 +0000 [thread overview]
Message-ID: <20251006230821.275642-1-easwar.hariharan@linux.microsoft.com> (raw)
Use a better mapping of hypervisor status codes to errno values and
disambiguate the catch-all -EIO value. While here, remove the duplicate
INVALID_LP_INDEX and INVALID_REGISTER_VALUES hypervisor status entries.
Fixes: 3817854ba89201 ("hyperv: Log hypercall status codes as strings")
Signed-off-by: Easwar Hariharan <easwar.hariharan@linux.microsoft.com>

Changes in v2: Change more values, delete duplicated entries
