GFS2: Remove gfs2_refresh_inode from inode creation path
The original method for creating inodes used in GFS2 was to fill out a buffer, with all the information, and then to read that buffer into the in-core inode, using gfs2_refresh_inode() The problem with this approach is that all the inode's fields need to be calculated ahead of time, and were stored in various variables making the code rather complicated. The new approach is simply to allocate the in-core inode earlier and fill in as many fields as possible ahead of time. These can then be used to initilise the on disk representation. The code has been working towards the point where it is possible to remove gfs2_refresh_inode() because all the fields are correctly initialised ahead of time. We've now reached that milestone, and have reversed the order of setting up the in core and on disk inodes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
