#3 NFS lockd support for file system locking

[Rob Gjertsen]

Description:
NFS advisory locking is performed by lockd on the
exporting node. It currently does its own local locking
without regard to the filesystem. Linux provides a lock
file operation that is used by non-NFS lock routines to
allow the exporting filesystem to handle such locks. In
the case of distributed filesystems like GPFS, this is
essential because locking on other nodes must be taken
into consideration when responding to lock requests.
This patch adds the lock calls that are necessary for
correct operation over NFS.

No longer required with SLES after SLES8 SP3 and SLES9.
Patch is needed with RHEL3 and RHEL4 (if using NFS locking
when exporting GPFS via NFS).

The standard procedure that we employ for applying a kernel
patch is:

1. "cd" to the root of the kernel source directory
(eg, cd /usr/src/linux) and copy the patch to this
directory.

2. Apply the patch via the command

patch -p1 < patch-name.patch

3. Then build and install the patched kernel according
to the instructions provided by the Linux distribution.
