Description

NFS filesystems monitored by FEM are ignored by several mdb walkers and dcmds. Here is an example of three NFS mounted filesystems (two of them are monitored by FEM):

> ::fsinfo!grep nfs
ffffff01ad7d6760 nfs             /nfs
ffffff01ad7d6590 nfs             /home/denis
ffffff01ad7d6930 nfs             /home/andrej
> ffffff01ad7d6760::print vfs_t vfs_op|::print vfsops_t vfs_mount
vfs_mount = fshead_mount
> ffffff01ad7d6590::print vfs_t vfs_op|::print vfsops_t vfs_mount
vfs_mount = fshead_mount
> ffffff01ad7d6930::print vfs_t vfs_op|::print vfsops_t vfs_mount
vfs_mount = nfs4_mount
>

The following walkers and dcmds are not aware about the monitored filesystems:

> ::walk nfs_vfs
ffffff01ad7d6930
> ::walk nfs4_mnt
ffffffa6649d6000
> ::walk nfs_mnt
> ::nfs_mntinfo 
> ::nfs4_mntinfo
