Message-Id: <20221126005756.7662-3-jefflexu@linux.alibaba.com> Date: Sat, 26 Nov 2022 08:57:56 +0800 From: Jingbo Xu <jefflexu@...ux.alibaba.com> To: xiang@...nel.org, chao@...nel.org, linux-erofs@...ts.ozlabs.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 2/2] erofs: enable large folio support for non-compressed format Enable large folio in both device and fscache mode. Then the readahead routine will pass down large folio containing multiple pages. Enable this feature for non-compressed format for now, until the compression part supports large folio later.
