Heinz had spotted that I'd forgotten to test in databuf_lo_add() that the data buffer in question hadn't already been added to the list. This was causing an infinite loop later on in the "before commit" routine. This means that GFS2 is now ready to be tested by everybody. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Two internal files which are read through the gfs2_internal_read() routine were already locked when the routine was called and this do not need locking at the redapages level. This patch introduces a struct file which is used as a sentinal so that readpage will only perform locking in the case that the struct file passed to it is _not_ equal to this sentinal. Since the comments in the generic kernel code indicate that the struct file will never be used for anything other than passing straight through to readpage(), this should be ok.

This patch adds back O_DIRECT support with various caveats attached: 1. Journaled data can be read via O_DIRECT since its now the same on disk format as normal data files. 2. Journaled data writes with O_DIRECT will be failed sliently back to normal writes (should we really do this I wonder or should we return an error instead?) 3. Stuffed files will be failed back to normal buffered I/O 4. All the usual corner cases (write beyond current end of file, write to an unallocated block) will also revert to normal buffered I/O. The I/O path is slightly odd as reads arrive at the page cache layer with the lock for the file already held, but writes arrive unlocked. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

There were one or two fields in structures which didn't get changed last time back to their gfs1 sizes and alignments. One or two constants have also changed back to their original values which were missed the first time. Its possible that indirect pointer blocks might need to change. If they don't we'll have to rewrite them all on upgrade due to a change in the amount of padding that they use. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Umount is now working correctly again. The bug was due to not getting an extra ref count when mounting the fs. We should have bumped it by two (once for the internal pointer to the root inode from the super block and once for the inode hanging off the dcache entry for root). Also this patch tidys up the code dealing with looking up and creating inodes. We now pass Linux inodes (with gfs2_inodes attached) rather than the other way around and this reduces code duplication in various places. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This is a very large patch, with a few still to be resolved issues so you might want to check out the previous head of the tree since this is known to be unstable. Fixes for the various bugs will be forthcoming shortly. This patch removes the special data format which has been used up till now for journaled data files. Directories still retain the old format so that they will remain on disk compatible with earlier releases. As a result you can now do the following with journaled data files: 1) mmap them 2) export them over NFS 3) convert to/from normal files whenever you want to (the zero length restriction is gone) In addition the level at which GFS' locking is done has changed for all files (since they all now use the page cache) such that the locking is done at the page cache level rather than the level of the fs operations. This should mean that things like loopback mounts and other things which touch the page cache directly should now work. Current known issues: 1. There is a lock mode inversion problem related to the resource group hold function which needs to be resolved. 2. Any significant amount of I/O causes an oops with an offset of hex 320 (NULL pointer dereference) which appears to be related to a journaled data buffer appearing on a list where it shouldn't be. 3. Direct I/O writes are disabled for the time being (will reappear later) 4. There is probably a deadlock between the page lock and GFS' locks under certain combinations of mmap and fs operation I/O. 5. Issue relating to ref counting on internally used inodes causes a hang on umount (discovered before this patch, and not fixed by it) 6. One part of the directory metadata is different from GFS1 and will need to be resolved before next release. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Update the function in GFS2 which deals with truncation of partial blocks. Some of the code is "borrowed" from ext3 since it appears to give a good model of how to do this operation. The function is renamed gfs2_block_truncate_page accordingly. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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).

Removing the gfs2_databuf structure and using gfs2_bufdata instead is a step towards allowing journaling of data without requiring the metadata header on each journaled block. The idea is to merge the code paths for ordered data with that of journaled data, with the log operations in lops.c tacking account of the different types of buffers as they are presented to it. Largely the code path for metadata will be similar too, but obviously through a different set of log operations. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>
