[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: Rationalise header files Move the contents of some headers which contained very little into more sensible places, and remove the original header files. This should make it easier to find things. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> 2008-10-14 19:05:55 +04:00			`#include <linux/fs.h>`

[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.

[GFS2] Remove lm.[ch] and distribute content The functions in lm.c were just wrappers which were mostly only used in one other file. By moving the functions to the files where they are being used, they can be marked static and also this will usually result in them being inlined since they are often only used from one point in the code. A couple of really trivial functions have been inlined by hand into the function which called them as it makes the code clearer to do that. We also gain from one fewer function call in the glock lock and unlock paths.

Revert "GFS2: Fix use-after-free bug on umount" This reverts commit 78802499912f1ba31ce83a94c55b5a980f250a43. The original patch is causing problems in relation to order of operations at umount in relation to jdata files. I need to fix this a different way.
