We're getting requests to allow the client to support btime, current kNFSD already supports this for compatible filesystems. I've rebased and worked the first three patches from https://lore.kernel.org/linux-nfs/20211227190504.309612-1-trondmy@xxxxxxxxxx/ onto v6.14, and I've been driving them around bakeathon without any signs of trouble yet this week. Thanks Trond and Anne for this (years-ago) work. v2 - fix unnecessary cast to printk v3 - drop hunk unrolling INVALID_ATTR on 2/3, add BTIME to INVALID_ATTR Anne Marie Merritt (1): nfs: Add timecreate to nfs inode Trond Myklebust (2): Expand the type of nfs_fattr->valid NFS: Return the file btime in the statx results when appropriate fs/nfs/inode.c | 34 +++++++++++++++++++---- fs/nfs/nfs4proc.c | 14 +++++++++- fs/nfs/nfs4trace.h | 3 ++- fs/nfs/nfs4xdr.c | 24 +++++++++++++++++ fs/nfs/nfstrace.h | 3 ++- include/linux/nfs_fs.h | 8 ++++++ include/linux/nfs_fs_sb.h | 2 +- include/linux/nfs_xdr.h | 57 ++++++++++++++++++++------------------- 8 files changed, 109 insertions(+), 36 deletions(-) -- 2.47.0
