[RFC PATCH] ACPICA: Tables: Fix regression introduced by a too early mechanism enabling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the Linux kernel side, acpi_get_table() hasn't been fully balanced by
acpi_put_table() invocations. So it is not a good timing to report errors.
The strict balanced validation count check should only be enabled after
confirming that all kernel side invocations are safe.

Thus this patch removes the fatal error but leaves the error report to
indicate the leak so that developers can notice the required engineering
change. Reported by Dan Williams, fixed by Lv Zheng.
