From 4fe70bcee2ec8515f123d8c826631b54bbf793e7 Mon Sep 17 00:00:00 2001 From: Jim McDonough Date: Thu, 9 Nov 2006 20:29:31 +0000 Subject: r19647: Add some GPFS support in a vfs mod. Also adds the kernel flock op to the vfs layer, since gpfs supports it. Thanks to Volker, Christian, Mathias, Chetan, and Peter.
