Modified files:
sys/nfsclient nfs_bio.c nfs_vnops.c
Log:
This change grabs the vnode lock for NFS client vnodes when calling
VOP_SETATTR() or VOP_GETATTR(); without these locks (a) VFS_DEBUG_LOCKS
will panic, and (b) it may be possible to corrupt entries in the cached
vnode attributes in the nfsnode, since nfsnode attribute cache data is
also protected by the vnode lock.
