Subject: NFSv4.1/pNFS: pnfs_mark_matching_lsegs_return must notify of layout return
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0bdb8fa6ecb4a356f26c6874db51b5488706e088;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

NFSv4.1/pNFS: pnfs_mark_matching_lsegs_return must notify of layout return

It's not sufficient to just mark the layout segment for layout return. We
also need to set the NFS_LAYOUT_RETURN_BEFORE_CLOSE flag in the layout header.
