[GFS2] Update copyright, tidy up incore.h As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this updates the copyright message to say "version" in full rather than "v.2". Also incore.h has been updated to remove forward structure declarations which are not required. The gfs2_quota_lvb structure has now had endianess annotations added to it. Also quota.c has been updated so that we now store the lvb data locally in endian independant format to avoid needing a structure in host endianess too. As a result the endianess conversions are done as required at various points and thus the conversion routines in lvb.[ch] are no longer required. I've moved the one remaining constant in lvb.h thats used into lm.h and removed the unused lvb.[ch]. I have not changed the HIF_ constants. That is left to a later patch which I hope will unify the gh_flags and gh_iflags fields of the struct gfs2_holder.

[GFS2] Make headers compile on their own As per Jan Engelhardt's comments, this should make all the headers compile on their own by including and/or declaring structures early. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

[GFS2] Spelling sentinal -> sentinel A spelling mistake (one of mine). Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

[GFS2] Add gfs2_internal_read() Add the new external read function. Its temporarily in jdata.c even though the protoype is in ops_file.h - this will change shortly. The current implementation will change to a page cache one when that happens. In order to effect the above changes, the various internal inodes now have Linux inodes attached to them. We keep the references to the Linux inodes, rather than the gfs2_inodes in the super block. In order to get everything to work correctly I've had to reorder the init sequence on mount (which I should probably have done earlier when .gfs2_admin was made visible).

[GFS2] Only set inode flags when required We were setting the inode flags from GFS2's flags far too often, even when they couldn't possibly have changed. This patch reduces the amount of flag setting going on so that we do it only when the inode is read in or when the flags have changed. The create case is covered by the "when the inode is read in" case. This also fixes a bug where we didn't set S_SYNC correctly. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
