Subject: nfs/localio: remove alignment size checking in nfs_is_local_dio_possible
X-Git-Tag: v6.19-rc1~27^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f50d0328d02fe38ba196a73c143e5d87e341d4f7;p=thirdparty%2Fkernel%2Flinux.git

nfs/localio: remove alignment size checking in nfs_is_local_dio_possible

This check to ensure dio_offset_align isn't larger than PAGE_SIZE is
no longer relevant (older iterations of NFS Direct was allocating
misaligned head and tail pages but no longer does, so this check isn't
needed).

Fixes: c817248fc831 ("nfs/localio: add proper O_DIRECT support for READ and WRITE")
