For some reason we had two different sets of code for reading in the superblock. This removes one of them in favour of the other. Also we don't need the temporary buffer for the sb since we already have one in the gfs2 sb itself. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

lm_interface.h has a few out of the tree clients such as GFS1 and userland tools. Right now, these clients keeps a copy of the file in their build tree that can go out of sync. Move lm_interface.h to include/linux, export it to userland and clean up fs/gfs2 to use the new location. Signed-off-by: NFabio M.

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.

This means that we don't need to create a special inode just to contain a struct address_space in order to read a single disk block. Instead we read the disk block directly. Its slightly faster, and uses slightly less memory, but the real reason for doing this is that it removes a special case from the glock code. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch fixes the way we have been dealing with unlinked, but still open files. It removes all limits (other than memory for inodes, as per every other filesystem) on numbers of these which we can support on GFS2. It also means that (like other fs) its the responsibility of the last process to close the file to deallocate the storage, rather than the person who did the unlinking. Note that with GFS2, those two events might take place on different nodes. Also there are a number of other changes: o We use the Linux inode subsystem as it was intended to be used, wrt allocating GFS2 inodes o The Linux inode cache is now the point which we use for local enforcement of only holding one copy of the inode in core at once (previous to this we used the glock layer). o We no longer use the unlinked "special" file. We just ignore it completely. This makes unlinking more efficient. o We now use the 4th block allocation state. The previously unused state is used to track unlinked but still open inodes. o gfs2_inoded is no longer needed o Several fields are now no longer needed (and removed) from the in core struct gfs2_inode o Several fields are no longer needed (and removed) from the in core superblock There are a number of future possible optimisations and clean ups which have been made possible by this patch.

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>

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>

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>

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).
