Subject: [RFC v2 3/3] blkdev: remove CONFIG_TRANSPARENT_HUGEPAGES dependency for LBS devices
Date: Sat, 6 Dec 2025 04:08:58 +0100 [thread overview]
Message-ID: <20251206030858.1418814-4-p.raghav@samsung.com> (raw)
In-Reply-To: <20251206030858.1418814-1-p.raghav@samsung.com>
Now that dependency between CONFIG_TRANSPARENT_HUGEPAGES and large
folios are removed, enable LBS devices even when THP config is disabled.
