[patch] nfs attribute cache mount options broken on CURRENT

[Jaakko Heinonen]

Hi,

nfs mount options acregmin, acregmax, acdirmin and acdirmax are broken
on CURRENT (unless you use an old mount_nfs binary which passes options
differently).

The problem is that nfs_mount() (in sys/nfsclient/nfs_vfsops.c) doesn't
set flags for those options when they are passed as string options. Also
the new code doesn't allow setting the options to 0 which is needed to
disable the attribute cache.

This patch should fix the problem:
