Hi,
> It seems more fixes are needed.
when compare btrfs subvol with xfs crossmnt, we found out
a new feature difference.
/mnt/test xfs
/mnt/text/xfs2 another xfs(crossmnt)
nfsd4_encode_dirent_fattr() report "/mnt/test/xfs2" + "/";
but
/mnt/test btrfs
/mnt/test/sub1 btrfs subvol
nfsd4_encode_dirent_fattr() report "/mnt/test/" + "sub1";
for '/mnt/test/sub1', nfsd should treat the mountpoint as
'/mn/test/sub1', rather than '/mnt/test'?
I'm sorry that yet no patch is avaliable, kernel source is quite
difficult for me.
Best Regards
