For non-static function declarations, external linkage is implied and the 'extern' keyword isn't needed. Some static checkers complain about the overuse of 'extern', so clean up all the function declarations.
In addition, remove 'extern' from the definition of free_local_statfs_inodes(); it isn't needed there, either.

gfs2: Only use struct gfs2_rbm for bitmap manipulations
GFS2 uses struct gfs2_rbm to represent a filesystem block number as a bit position within a resource group. This representation is used in the bitmap manipulation code to prevent excessive conversions between block numbers and bit positions, but also in struct gfs2_blkreserv which is part of struct gfs2_inode, to mark the start of a reservation. In the inode, the bit position representation makes less sense: first, the start position is used as a block number about as often as a bit position; second, the bit position representation makes the code unnecessarily complicated and difficult to read.
Therefore, change struct gfs2_blkreserv to represent the start of a reservation as a block number instead of a bit position. (This requires keeping track of the resource group in gfs2_blkreserv separately.) With that change, various things can be slightly simplified, and struct gfs2_rbm can be moved to rgrp.c.

gfs2: new slab for transactions
This patch adds a new slab for gfs2 transactions. That allows us to reduce kernel memory fragmentation, have better organization of data for analysis of vmcore dumps. A new centralized function is added to free the slab objects, and it exposes use-after-free by giving warnings if a transaction is freed while it still has bd elements attached to its buffers or ail lists. We make sure to initialize those transaction ail lists so we can check their integrity when freeing.
At a later time, we should add a slab initialization function to make it more efficient, but for this initial patch I wanted to minimize the impact.

gfs2: Eliminate redundant ip->i_rgd
GFS2 remembers the last rgrp used for allocations in ip->i_rgd. However, block allocations are made by way of a reservations structure, ip->i_res, which keeps the last rgrp in ip->i_res.rs_rgd, and ip->i_res is kept in sync with ip->i_res.rs_rgd, so it's redundant. Get rid of ip->i_rgd and just use ip->i_res.rs_rgd in its place.

GFS2: Split gfs2_trans_add_bh() into two
There is little common content in gfs2_trans_add_bh() between the data and meta classes by the time that the functions which it calls are taken into account. The intent here is to split this into two separate functions. Stage one is to introduce gfs2_trans_add_data() and gfs2_trans_add_meta() and update the callers accordingly.
Later patches will then pull in the content of gfs2_trans_add_bh() and its dependent functions in order to clean up the code in this area.

GFS2: Remove rs_requested field from reservations
The rs_requested field is left over from the original allocation code, however this should have been a parameter passed to the various functions from gfs2_inplace_reserve() and not a member of the reservation structure as the value is not required after the initial allocation.
This also helps simplify the code since we no longer need to set the rs_requested to zero. Also the gfs2_inplace_release() function can also be simplified since the reservation structure will always be defined when it is called, and the only remaining task is to unlock the rgrp if required. It can also now be called unconditionally too, resulting in a further simplification.

GFS2: Extend the life of the reservations
This patch lengthens the lifespan of the reservations structure for inodes. Before, they were allocated and deallocated for every write operation. With this patch, they are allocated when the first write occurs, and deallocated when the last process closes the file. It's more efficient to do it this way because it saves GFS2 a lot of unnecessary allocates and frees. It also gives us more flexibility for the future: (1) we can now fold the qadata structure back into the structure and save those alloc/frees, (2) we can use this for multi-block reservations.

GFS2: Cache the most recently used resource group in the inode
This means that after the initial allocation for any inode, the last used resource group is cached in the inode for future use. This drastically reduces the number of lookups of resource groups in the common case, and this the contention on that data structure.
The allocation algorithm is the same as previously, except that we always check to see if the goal block is within the cached rgrp first before going to the rbtree to look one up.

GFS2: Use rbtree for resource groups and clean up bitmap buffer ref count scheme
Here is an update of Bob's original rbtree patch which, in addition, also resolves the rather strange ref counting that was being done relating to the bitmap blocks.
Originally we had a dual system for journaling resource groups. The metadata blocks were journaled and also the rgrp itself was added to a list. The reason for adding the rgrp to the list in the journal was so that the "repolish clones" code could be run to update the free space, and potentially send any discard requests when the log was flushed. This was done by comparing the "cloned" bitmap with what had been written back on disk during the transaction commit.
Due to this, there was a requirement to hang on to the rgrps' bitmap buffers until the journal had been flushed. For that reason, there was a rather complicated set up in the ->go_lock ->go_unlock functions for rgrps involving both a mutex and a spinlock (the ->sd_rindex_spin) to maintain a reference count on the buffers.
However, the journal maintains a reference count on the buffers anyway, since they are being journaled as metadata buffers. So by moving the code which deals with the post-journal accounting for bitmap blocks to the metadata journaling code, we can entirely dispense with the rather strange buffer ref counting scheme and also the requirement to journal the rgrps.
The net result of all this is that the ->sd_rindex_spin is left to do exactly one job, and that is to look after the rbtree or rgrps.
This patch is designed to be a stepping stone towards using RCU for the rbtree of resource groups, however the reduction in the number of uses of the ->sd_rindex_spin is likely to have benefits for multi-threaded workloads, anyway.
The patch retains ->go_lock and ->go_unlock for rgrps, however these maybe also be removed in future in favour of calling the functions directly where required in the code. That will allow locking of resource groups without needing to actually read them in - something that could be useful in speeding up statfs.
In the mean time though it is valid to dereference ->bi_bh only when the rgrp is locked. This is basically the same rule as before, modulo the references not being valid until the following journal flush.

GFS2: fallocate support
This patch adds support for fallocate to gfs2. Since the gfs2 does not support uninitialized data blocks, it must write out zeros to all the blocks. However, since it does not need to lock any pages to read from, gfs2 can write out the zero blocks much more efficiently. On a moderately full filesystem, fallocate works around 5 times faster on average. The fallocate call also allows gfs2 to add blocks to the file without changing the filesize, which will make it possible for gfs2 to preallocate space for the rindex file, so that gfs2 can grow a completely full filesystem.

[GFS2] Update gfs2_trans_add_unrevoke to accept extents
By adding an extra argument to gfs2_trans_add_unrevoke we can now specify an extent length of blocks to unrevoke. This means that we only need to make one pass through the list for each extent rather than each block. Currently the only extent length which is used is 1, but that will change in the future.
Also gfs2_trans_add_unrevoke is removed from gfs2_alloc_meta since its the only difference between this and gfs2_alloc_data which is left. This will allow a future patch to merge these two functions into one (i.e. one call to allocate both data and metadata in a single extent in the future).

[GFS2] Don't add glocks to the journal
The only reason for adding glocks to the journal was to keep track of which locks required a log flush prior to release. We add a flag to the glock to allow this check to be made in a simpler way.
This reduces the size of a glock (by 12 bytes on i386, 24 on x86_64) and means that we can avoid extra work during the journal flush.

[GFS2] Clean up gfs2_trans_add_revoke()
The following alters gfs2_trans_add_revoke() to take a struct gfs2_bufdata as an argument. This eliminates the memory allocation which was previously required by making use of the already existing struct gfs2_bufdata. It makes some sanity checks to ensure that the gfs2_bufdata has been removed from all the lists before its recycled as a revoke structure. This saves one memory allocation and one free per revoke structure.
Also as a result, and to simplify the locking, since there is no longer any blocking code in gfs2_trans_add_revoke() we must hold the log lock whenever this function is called. This reduces the amount of times we take and unlock the log lock.
