From 2915ed2c92dd349203070eea8970fd4fb62ba5b4 Mon Sep 17 00:00:00 2001
From: KB <kb@sysmikro.com.pl>
Date: Sat, 28 May 2016 20:55:19 +0200
Subject: [PATCH 6/7] struct inode embedded in vxfs_vfs_inode

struct vxfs_vfs_inode is allocated from vxfs_inode_cachep
and vfs inode is initialized by inode_constructor().
sb->s_op must be set before read_fshead() otherwise 
3 inodes will be allocated from common inode_cachep.

 	  FreeVxFS is a file system driver that support the VERITAS VxFS(TM)
 	  file system format.  VERITAS VxFS(TM) is the standard file system
 	  of SCO UnixWare (and possibly others) and optionally available
-	  for Sunsoft Solaris, HP-UX and many other operating systems.
+	  for Sunsoft Solaris, HP-UX and many other operating systems. However
+	  these particular OS implementations of vxfs may differ in on-disk
+	  data endianess and/or superblock offset. The vxfs module has been 
+	  tested with SCO UnixWare and HP-UX B.10.20 (pa-risc 1.1 arch.)
 	  Currently only readonly access is supported.
 
 	  NOTE: the file system type as used by mount(1), mount(2) and
 	  fstab(5) is 'vxfs' as it describes the file system format, not
 	  the actual driver.
 
+	  There is a userspace utility for HP-UX logical volumes which makes 
+	  creating HP-UX logical volumes easy from HP-UX disk block device file 
+	  or regular file with image of the disk. See:
+	         https://sourceforge.net/projects/linux-vxfs/
+
 	  To compile this as a module, choose M here: the module will be
 	  called freevxfs.  If unsure, say N.
