Subject: [RFC PATCH v2 3/3] ACPI: extlog: Make print_extlog_rcd() log unconditionally
Date: Fri, 10 May 2024 13:21:47 +0200 [thread overview]
Message-ID: <20240510112740.667445-4-fabio.m.de.francesco@linux.intel.com> (raw)
In-Reply-To: <20240510112740.667445-1-fabio.m.de.francesco@linux.intel.com>
Make extlog_print_rcd() log unconditionally to report errors even if
userspace is not consuming trace events. Remove ras_userspace_consumers()
because it is not anymore used.
This change makes extlog_print() (ELOG) log consistently with ghes_proc()
(GHES).
