2008-01-25[GFS2] Remove function gfs2_get_blockBob Peterson
This patch is just a cleanup. Function gfs2_get_block() just calls function gfs2_block_map reversing the last two parameters. By reversing the parameters, gfs2_block_map() may be called directly and function gfs2_get_block may be eliminated altogether. Since this function is done for every block operation, this streamlines the code and makes it a little bit more efficient.

2008-01-25[GFS2] Introduce gfs2_set_aops()Steven Whitehouse
Just like ext3 we now have three sets of address space operations to cover the cases of writeback, ordered and journalled data writes. This means that the individual operations can now become less complicated as we are able to remove some of the tests for file data mode from the code.

2008-01-25[GFS2] Clean up internal read functionSteven Whitehouse
As requested by Christoph, this patch cleans up GFS2's internal read function so that it no longer uses the do_generic_mapping_read function. This function is obsolete and GFS2 is the last user of it. As a side effect the internal read code gets smaller and easier to read and gfs2_readpage is split into two. One function has the locking and the other function has the rest of the logic. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> Cc: Christoph Hellwig <hch@infradead.org>
2007-07-09[GFS2] Addendum patch 2 for gfs2_growRobert Peterson
This addendum patch 2 corrects three things: 1. It fixes a stupid mistake in the previous addendum that broke gfs2. Ref: https://www.redhat.com/archives/cluster-devel/2007-May/msg00162.html 2. It fixes a problem that Dave Teigland pointed out regarding the external declarations in ops_address.h being in the wrong place. 3. It recasts a couple more %llu printks to (unsigned long long) as requested by Steve Whitehouse. I would have loved to put this all in one revised patch, but there was a rush to get some patches for RHEL5. Therefore, the previous patches were applied to the git tree "as is" and therefore, I'm posting another addendum. Sorry.

2007-07-09[GFS2] kernel changes to support new gfs2_grow commandRobert Peterson
This is another revision of my gfs2 kernel patch that allows gfs2_grow to function properly. Steve Whitehouse expressed some concerns about the previous patch and I restructured it based on his comments. The previous patch was doing the statfs_change at file close time, under its own transaction. The current patch does the statfs_change inside the gfs2_commit_write function, which keeps it under the umbrella of the inode transaction. I can't call ri_update to re-read the rindex file during the transaction because the transaction may have outstanding unwritten buffers attached to the rgrps that would be otherwise blown away. So instead, I created a new function, gfs2_ri_total, that will re-read the rindex file just to total the file system space for the sake of the statfs_change. The ri_update will happen later, when gfs2 realizes the version number has changed, as it happened before my patch. Since the statfs_change is happening at write_commit time and there may be multiple writes to the rindex file for one grow operation. So one consequence of this restructuring is that instead of getting one kernel message to indicate the change, you may see several. For example, before when you did a gfs2_grow, you'd get a single message like: GFS2: File system extended by 247876 blocks (968MB) Now you get something like: GFS2: File system extended by 207896 blocks (812MB) GFS2: File system extended by 39980 blocks (156MB) This version has also been successfully run against the hours-long "gfs2_fsck_hellfire" test that does several gfs2_grow and gfs2_fsck while interjecting file system damage. It does this repeatedly under a variety Resource Group conditions. Signed-off-By: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-05[GFS2] Make headers compile on their ownSteven Whitehouse
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>
2006-09-01[GFS2] Update copyright, tidy up incore.hSteven Whitehouse
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.

2006-07-11[GFS2] Add generation numberSteven Whitehouse
This adds a generation number for the eventual use of NFS to the ondisk inode. Its backward compatible with the current code since it doesn't really matter what the generation number is to start with, and indeed since its set to zero, due to it being taken from padding in both the inode and rgrp header, it should be fine. The eventual plan is to use this rather than no_formal_ino in the NFS filehandles. At that point no_formal_ino will be unused. At the same time we also add a releasepages call back to the "normal" address space for gfs2 inodes. Also I've removed a one-linrer function thats not required any more.
