Martin Brandenburg 3c9cf98d7b orangefs: rename orangefs_inode_getattr to orangefs_inode_old_getattr
This is motivated by orangefs_inode_old_getattr's habit of writing over
live inodes.

Martin Brandenburg 933287da75 orangefs: Implement inode_operations->permission().
Thus d_revalidate is not obliged to check on as much, which will
eventually lead the way to hammering the filesystem servers much less.

Martin Brandenburg 99109822f5 orangefs: Fix revalidate.
Previously, it would update a live inode. This was fixed, but it did not
ever check that the inode attributes in the dcache are correct. This
checks all inode attributes and rejects any that are not correct, which
causes a lookup and thus a new getattr.

Perhaps inode_operations->permission should replace or augment some of
this.

There is no actual caching, and this does a rather excessive amount of
network operations back to the filesystem server.

Yi Liu 8bb8aefd5a OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.
OrangeFS was formerly known as PVFS2 and retains the name in many places.

I leave the device /dev/pvfs2-req since this affects userspace.

I leave the filesystem type pvfs2 since this affects userspace. Further
the OrangeFS sysint library reads fstab for an entry of type pvfs2
independently of kernel mounts.

I leave extended attribute keys user.pvfs2 and system.pvfs2 as the
sysint library understands these.

I leave references to userspace binaries still named pvfs2.

I leave the filenames.
