Subject: [PATCH] f2fs: preload extent_cache for POSIX_FADV_WILLNEED
Date: Tue, 19 Sep 2023 17:46:45 -0700	[thread overview]
Message-ID: <20230920004645.1462354-1-jaegeuk@kernel.org> (raw)

This patch tries to preload extent_cache given POSIX_FADV_WILLNEED, which is
more useful for generic usecases.
