Update the debugging code in trans.c and at the same time improve the debugging code for gfs2_holders. The new code should be pretty fast during the normal case and provide just as much information in case of errors (or more). One small function from glock.c has moved to glock.h as a static inline so that its return address won't get in the way of the debugging. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Replace the lock_for_trans()/lock_for_flush() functions with an rwsem. In fact the sd_log_flush_lock becomes an rwsem (the write part of it) and is extended slightly to cover everything that the lock_for_flush() used to cover. The read part of the lock is instead of lock_for_trans(). This corrects the races in the original code and reduces the code size. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This reduces the size of the directory code by about 3k and gets readdir() to use the functions which were introduced in the previous directory code update. Two memory allocations are merged into one. Eliminates zeroing of some buffers which were never used before they were initialised by other data. There is still scope for further improvement in the directory code. On the logging side, a hand created mutex has been replaced by a standard Linux mutex in the log allocation code.

Due to a typo, the dir leaf split operation was (for the first split in a directory) writing the new hash vaules at the wrong offset. This is now fixed. Also some other tidy ups are included: - We use GFS2's hash function for dentries (see ops_dentry.c) so that we don't have to keep recalculating the hash values. - A lot of common code is eliminated between the various directory lookup routines. - Better error checking on directory lookup (previously different routines checked for different errors) - The leaf split operation has a couple of redundant operations removed from it, so it should be faster. There is still further scope for further clean ups in the directory code, and readdir in particular could do with slimming down a bit. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

In order to separate out the filesystem's metadata from "normal" files and directories, a new filesystem type has been created. It is called gfs2meta and mounting it gives access to the files that were previously under .gfs2_admin (well still are until mkfs is altered, which is next on the adgenda). Its not currently possible to mount both gfs2 and gfs2meta on the same block device at the same time. A future patch will allow that to happen. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

We no longer lookup ".gfs2_admin" in the root directory in order to find it, but instead use the inode number given in the superblock. Both the root directory and the admin directory are now looked up using the same routine, so the redundant code is removed. Also, there is no longer a reference to the root inode in the GFS2 super block. When required this can be retreived via sb->s_root->d_inode instead. Assuming that we introduce a metadata filesystem type for GFS, then this is a first step towards that goal. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

As suggested by Pekka Enberg <penberg@cs.helsinki.fi>. The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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.

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>

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).
