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.

This results in smaller list heads, so that we can have more chains in the same amount of memory (twice as many). I've multiplied the size of the table by four though - this is because we are saving memory by not having one lock per chain any more. So we land up using about the same amount of memory for the hash table as we did before I started these changes, the difference being that we now have four times as many hash chains. The reason that I say "about the same amount of memory" is that the actual amount now depends upon the NR_CPUS and some of the config variables, so that its not exact and in some cases we do use more memory. Eventually we might want to scale the hash table size according to the size of physical ram as measured on module load. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

There are several reasons why we want to do this: - Firstly its large and thus we'll scale better with multiple GFS2 fs mounted at the same time - Secondly its easier to scale its size as required (thats a plan for later patches) - Thirdly, we can use kzalloc rather than vmalloc when allocating the superblock (its now only 4888 bytes) - Fourth its all part of my plan to eventually be able to use RCU with the glock hash.

As per Jan Engelhardt's second email, this removes some unused code, and fixes up indenting in various places. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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.

We can take advantage of the slab allocator to ensure that all the list heads and the spinlock (plus one or two other fields) are initialised by slab to speed up allocation of glocks. 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 adds some extra debugging to glock.c and changes inode.c's deallocation code to call the debugging code at a suitable moment. I'm chasing down a particular bug to do with deallocation at the moment and the code can go again once the bug is fixed. Also this includes the first part of some changes to unify the Linux struct inode and GFS2's struct gfs2_inode. This transformation will happen in small parts over the next short period.

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>

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>
